This fixes the testcases that are failing due to my recent patch.
It turns out that the start address across baremetal and linux builds
isn't entirely predictable without a linker script. Since the address
themselves are not the important thing I am ignoring them now.
Secondly I was encoding data using .word using non 0 values, however
because .word is subjected to endiannes these non-zero values under
big-endian happen to fall into the encoding space of instructions which
changes the disassembly. Using 0 fixes this problem and the purpose of
the test still holds, though objdump will dump ... for data only sections,
which is ok as the data/insn mixed sections will test the patch.
The ARM Attributes sections is not important and is ignored.

Similar to the AArch64 patches the Arm disassembler has the same issues with
out of order sections but also a few short comings.
For one thing there are multiple code blocks to determine mapping symbols, and
they all work slightly different, and neither fully correct. The first thing
this patch does is centralise the mapping symbols search into one function
mapping_symbol_for_insn. This function is then updated to perform a search in
a similar way as AArch64.
Their used to be a value has_mapping_symbols which was used to determine the
default disassembly for objects that have no mapping symbols. The problem with
the approach was that it was determining this value in the same loop that needed
it, which is why this field could take on the states -1, 0, 1 where -1 means
"don't know". However this means that until you actually find a mapping symbol
or reach the end of the disassembly glob, you don't know if you did the right
action or not, and if you didn't you can't correct it anymore.
This is why the two jump-reloc-veneers-* testcases end up disassembling some
insn as data when they shouldn't.
Out of order here refers to an object file where sections are not listed in a
monotonic increasing VMA order.
The ELF ABI for Arm [1] specifies the following for mapping symbols:
1) A text section must always have a corresponding mapping symbol at it's
start.
2) Data sections do not require any mapping symbols.
3) The range of a mapping symbol extends from the address it starts on up to
the next mapping symbol (exclusive) or section end (inclusive).
However there is no defined order between a symbol and it's corresponding
mapping symbol in the symbol table. This means that while in general we look
up for a corresponding mapping symbol, we have to make at least one check of
the symbol below the address being disassembled.
When disassembling different PCs within the same section, the search for mapping
symbol can be cached somewhat. We know that the mapping symbol corresponding to
the current PC is either the previous one used, or one at the same address as
the current PC.
However this optimization and mapping symbol search must stop as soon as we
reach the end or start of the section. Furthermore if we're only disassembling
a part of a section, the search is a allowed to search further than the current
chunk, but is not allowed to search past it (The mapping symbol if there, must
be at the same address, so in practice we usually stop at PC+4).
lastly, since only data sections don't require a mapping symbol the default
mapping type should be DATA and not INSN as previously defined, however if the
binary has had all its symbols stripped than this isn't very useful. To fix
this we determine the default based on the section flags. This will allow the
disassembler to be more useful on stripped binaries. If there is no section
than we assume you to be disassembling INSN.

The documentation for -D says that on Arm platforms -D should disassemble
data as instructions.
"If the target is an ARM architecture this switch also has the effect of
forcing the disassembler to decode pieces of data found in code sections
as if they were instructions. "
This makes it do as it says on the tincan so it's more consistent with
aarch32. The usecase here is for baremetal developers who have created
their instructions using .word directives instead if .insn.
Though for Linux users I do find this behavior somewhat non-optimal.
Perhaps there should be a new flag that just disassembles the values
following the actual mapping symbol?

My previous patch for AArch64 was not enough to catch all the cases where
disassembling an out-of-order section could go wrong. It had missed the case
DATA sections could be incorrectly disassembled as TEXT.
Out of order here refers to an object file where sections are not listed in a
monotonic increasing VMA order.
The ELF ABI for AArch64 [1] specifies the following for mapping symbols:
1) A text section must always have a corresponding mapping symbol at it's

opcodes/ChangeLog:
* aarch64-dis.c (print_insn_aarch64): Update the mapping symbol search
order.
The AArch64 disassembler has an optimization that it uses to reduce the amount
it has to search for mapping symbols during disassembly. This optimization
assumes that sections are listed in the section header in monotonic increasing
VMAs. However this is not a requirement for the ELF specification.
Because of this when such "out of order" sections occur the disassembler would
pick the wrong mapping symbol to disassemble the section with.
This fixes it by explicitly passing along the stop offset for the current
disassembly glob and when this changes compared to the previous one we've seen
the optimization won't be performed. In effect this restarts the search from
a well defined starting point. Usually the symbol's address.
The existing stop_vma can't be used for this as it is allowed to be unset and
setting this unconditionally would change the semantics of this field.

This allows checking the command line parsing more easily than before by
allowing many command line invokations from the same .d file.
Each line is used as a set of flags, and the tests are ran against the output
of the assembler with each set.
Each line of assembler is treated as another set of tests (as if the test file
were copied to another with a different #as: line).

The size tool currently defaults to berkeley format output. However,
this output format has a weird quirk, read-only data is counted
against the text sections, not the data sections.
The code offers no real explanation for why this is, but I'm reluctant
to change it for two reasons, first, I'm assuming it probably makes
sense in some case that I'm not thinking of (maybe a target where
sections are not marked executable, and so there's no distinction
between read-only data and code), and second, the code has been this
way for at least 20 years, I worry that changing things now might
cause more confusion than it solves.
This commit then introduces a new output format for the size tool,
this new format displays the results in a similar manor to the
berkeley format, but counts read-only data in the data column, and
only executable sections are counted in the text column.
Given that this is a brand new output format I've gone ahead and
simplified things a little, while the berkeley format displays the
total twice, once in decimal and once in hex, the new display format
just displays the total in decimal. Of course, there's still the
'--radix' option which can be used to display all the results in
hexadecimal or octal.
I've called the new format 'gnu', so '--format=gnu' or '-G' are used
to access it.

Linkers group input note sections with the same name into one output
note section with the same name. One output note section is placed in
one PT_NOTE segment. New linkers merge all input .note.gnu.property
sections into one output .note.gnu.property section with a single
NT_GNU_PROPERTY_TYPE_0 note in a single PT_NOTE segment. Since older
linkers treat input .note.gnu.property section as a generic note section
and just concatenate all input .note.gnu.property sections into one
output .note.gnu.property section without merging them, we may
see one or more NT_GNU_PROPERTY_TYPE_0 notes in PT_NOTE segment, which
are invalid.
GNU_PROPERTY_X86_UINT32_VALID was defined to address this issue such
that linker sets the bit for non-relocatable outputs. But it isn't
sufficient:
1. It doesn't cover generic properties.
2. When -mx86-used-note=yes is passed to x86 assembler, the
GNU_PROPERTY_X86_UINT32_VALID bit is set in GNU_PROPERTY_X86_ISA_1_USED
property in object file and older linkers generate invalid
NT_GNU_PROPERTY_TYPE_0 notes with the GNU_PROPERTY_X86_UINT32_VALID bit
set.
I am proposing the following changes:
1. Add PT_GNU_PROPERTY segment type:
# define PT_GNU_PROPERTY (PT_LOOS + 0x474e553)
which covers .note.gnu.property section.
2. Remove GNU_PROPERTY_X86_UINT32_VALID.

This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code. It adds a limit to the amount of
recursion that is allowed, before an error is triggered. It also adds a
new demangling option to disable this limit. (The limit is enabled by
default).

run_dump_test proposes an ld action but when trying to make use of it in
a gas test it gave me some Tcl error. It turns out that it references
the check_shared_lib_support procedure and ld_elf_shared_opt variable
both only available in ld-lib.exp. I've thus moved the procedure in
binutils-common.exp and defined the variable needed in the various
default.exp of testsuite that seem to be using run_dump_test.
Since check_shared_lib_support itself references the ld variable not
defined in binutils-common I've defined it from LD in run_dump_test and
fixed LD and LDFLAGS to be defined as expected by run_dump_test in the
various default.exp of testsuite using run_dump_test.

This is the result of an email thread starting here:
https://sourceware.org/ml/binutils/2018-09/msg00031.html
The main point of the thread is this observation:
* Supposing we had an object file with two globals, SomeGlobal and
SomeOtherGlobal, if one were to do "--globalize-symbol SomeGlobal
--keep-global-symbol SomeOtherGlobal", you might expect that both
SomeGlobal and SomeOtherGlobal are global in the output file... but it
isn't. Because --keep-global-symbol is set and doesn't include
SomeGlobal, SomeGlobal will be demoted to a local symbol. And because
the check to see if we should apply the --globalize-symbol flag checks
"flags" (the original flag set), and not "sym->flags", it decides not
to do anything, so SomeGlobal remains a local symbol. Although this is
a weird edge case, should this be changed so that --keep-global-symbol
implicitly keeps anything also specified via --globalize-symbol? (The
code seems technically correct with respect to the documentation, but
IMO the behavior is counter-intuitive).

--keep-global-symbol(s) and the --globalize-symbol(s) options are
