796d6298bb Arm: Fix Arm disassembler mapping symbol search. 
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.

c0c468d562 [ARM] Update bfd's Tag_CPU_arch knowledge 
BFD's bfd_get_mach () function returns a bfd specific value representing
the architecture of the target which is populated from the Tag_CPU_arch
build attribute value of that target. Among other users of that
interfacem, objdump which uses it to print the architecture version of
the binary being examinated and to decide what instruction is available
if run with "-m arm" via its own mapping from bfd_mach_arm_X values to
feature bits available.

However, both BFD and objdump's most recent known architecture is
Armv5TE. When encountering a newer architecture bfd_get_mach will return
bfd_mach_arm_unknown. This is unfortunate since objdump uses that value
to allow all instructions on all architectures which is already what it
does by default, making the "-m arm" trick useless.

This patch updates BFD and objdump's knowledge of Arm architecture
versions up to the latest Armv8-M Baseline and Mainline, Armv8-R and
Armv8.4-A architectures. Since several architecture versions (eg. 8.X-A)
share the same Tag_CPU_arch build attribute value and
bfd_mach_arm values, the mapping from bfd machine value to feature bits
need to return the most featureful feature bits that would yield the
given bfd machine value otherwise some instruction would not disassemble
under "-m arm" mode. The patch rework that mapping to make this clearer
and simplify writing the mapping rules. In particular, for simplicity
all FPU instructions are allowed in all cases.

Finally, the patch also rewrite the cpu_arch_ver table in GAS to use the
TAG_CPU_ARCH_X macros rather than hardcode their value.

7f923b7fd2 ELF dynsyms 
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations.  This happens before the
dynamic relocations are output, and the need for those symbols
determined.  In most cases they are not needed.  A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.

The patch also runs the new pr23161 and pr23162 tests on more targets.

df5f2391f7 ld error/warning messages 
This patch standardizes messages in ld, to better conform to the GNU
coding standard.  Besides issues of capitalization and full-stops,
I've
- Split up help messages for target options, so that adding a new
  option does not mean loss of translation for all the others.
- Embedded tabs have been removed, since a user might have tab stops
  set at other than 8 char intervals.
- Added missing program name (%P).  ld isn't the compiler.
- Put %F and %X first (and removed %X if %F was present).  These can
  go anywhere, but look silly in the m%Fiddle of a message, and
  choosing "%P%F:" in some messages but "%F%P:" in others leads to the
  likelihood of duplication in ld.pot.  Besides, the colon belongs
  with %P.

some multi-line error messages, which don't fit particularly well with
the GNU coding standard insistence that error messages shouldn't be
capitalized or have a full-stop.  I've replaced the line breaks with
semicolons.

So for instance the following
  system/path/to/ld: myobject.o: invalid special symbol `foo'.
  system/path/to/ld: It must be a global or weak function symbol.
becomes
  system/path/to/ld: myobject.o: invalid special symbol `foo'; it must be a global or weak function symbol

d3a49aa80b readelf ngettext fixes 
This patch is a first pass at fixing readelf message pluralization.
I've deliberately not fixed the "out of memory" errors since it's very
unlikely that they will ever be complaining about not being able to
allocate for a single entry, and a few others where the size is very
unlikely to be 1 byte.

Then there are messages like this one:
"Out of %lu items there are %zu bucket clashes (longest of %zu entries).\n"
I suppose this could be split into three parts, "Of %lu items ",
"there are %zu bucket clashes ", and "(longest of %zu entries).\n",
each part being printed separately, but that might not be ideal for
sentence construction in other languages.  For now I'm punting on this
one.

Changes to readelf output require lots of testsuite adjustment..

4062f504eb As Alan predicted at https://sourceware.org/ml/binutils/2017-10/msg00137.html the values in some Arm tests need updating after recent changes. These looked a bit spooky at first, but they are just a difference in the order we emit veneers and far jumps, so are not so scary after all.

When ld is running with something other than --hash-style=sysv by

bff0500d7a [ARM] Add linker support for ARMv8-R 
=== Context ===

This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in the linker.

=== Patch description ===

This patch is composed of 3 changes:

1) The main change is the addition of the logic for merging a file whose
Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are
merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into
ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to
merge merge with ARMv8-R. Note that merging only occurs if the two
profiles are identical or one is S (Application or Realtime) and the
other is R.

2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop
are updated according to capabilities of ARMv8-R and their BFD_ASSERT
updated to reflect that the logic is valid for ARMv8-R.

3) 2 build attribute merging tests are added to test the first change.

046734ff42 Make import libraries relocatable objects 
For ELF targets --out-implib currently generates an executable file
(e_type is ET_EXEC) despite the file being expected to be linked against
some other object file to make an executable later. It seems therefore
more sensible to make the import library a relocatable object file
(e_type set to ET_REL).

Incidentally, as dicted by requirement 8 of
"ARM v8-M Security Extensions: Requirements on Development Tools"
(document ARM-ECM-0359818) version 1.0, import libraries generated when
using --cmse-implib *must* be relocatable object file so this commit
also adds an assert there in case the type of ELF import library is
changed again in the future.

	* elflink.c (elf_output_implib): Remove executable flag from import

	of import library and executable produced.

5474d94f03 dynrelro section for read-only dynamic symbols copied into executable 
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

4ade44b727 Set dynamic tag VMA and size from dynamic section when possible 
Rather than searching the output for a specific named section, it's

section name, making it possibile to map dynamic sections differently.
