PR25569, PDP11 ld -s clobbers last data byte
This patch fixes an ancient wart in aout support, in that text and
data section sizes are rounded up for alignment rather that just the
corresponding header sizes. Changing section sizes could conceivably
result in buffer overflows if section contents were held in memory.
Also, keeping the original section sizes allows this PR to be fixed
nicely.

_bfd_mul_overflow
This patch removes the bfd_alloc2 series of memory allocation functions,
replacing them with __builtin_mul_overflow followed by bfd_alloc. Why
do that? Well, a followup patch will implement _bfd_alloc_and_read
and I don't want to implement alloc2 variants as well.

bfd_size_type to size_t
bfd_size_type was invented a long time ago in the K&R days. Many
places in binutils ought to be using size_t instead (and there are
lots of places that use long or unsigned long that really ought to use
size_t too). Note that you can't change everything over to size_t: A
32-bit host needs a larger type than size_t to support reading and
processing of 64-bit ELF object files. This patch just tidies some
of the more obvious uses of bfd_size_type that could be size_t. There
no doubt are more lurking in the source. Incidentally, practically
all functions used for output of object files can use size_t and don't
need to worry about overflow of size expressions. If you have
something like
symcount * sizeof (void *)
when symcount is counting symbols already in memory then you know that
this expression can't overflow since the size of a symbol in memory is
larger by far than that of a pointer.

Use GCC LTO wrapper to get real symbols from LTO IR objects
GCC LTO wrapper is needed to extract real symbols from LTO IR objects.
This patch does the following:
1. Set up GCC LTO wrapper for each LTO IR object.
2. Run GCC LTO wrapper to get the real object.
3. Extract symbol info from the real object.
4. Cleanup afterwards.

ELF: Support the section flag 'o' in .section directive
As shown in
https://sourceware.org/bugzilla/show_bug.cgi?id=25490
--gc-sections will silently remove __patchable_function_entries section
and generate corrupt result. This patch adds the section flag 'o' to
.section directive:
.section __patchable_function_entries,"awo",@progbits,foo
.section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat
.section __patchable_function_entries,"awo",@progbits,bar,unique,4
.section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat,unique,1
which specifies the symbol name which the section references. Assmebler
will set its elf_linked_to_section to a local section where the symbol
is defined.
Linker is updated to call mark_hook if gc_mark of any of its linked-to
sections is set after all sections, except for backend specific ones,
have been garbage collected.

ELF: Add support for unique section ID to assembler
Clang's integrated assembler supports multiple section with the same
name:
.section .text,"ax",@progbits,unique,1
nop
.section .text,"ax",@progbits,unique,2
nop
"unique,N" assigns the number, N, as the section ID, to a section. The
valid values of the section ID are between 0 and 4294967295. It can be
used to distinguish different sections with the same section name.
This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.
This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id. It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

Tidy bfd.pot
This patch removes the leak of Nick's source directory into bfd.pot,
and emits #line for some generated files so that those files aren't
referenced by comments in the .pot file. You can see both of these
effects in the following diff. I've also removed use of an
unnecessary temp file in the make rules.

This implements register saving and restoring in the __tls_get_addr
call stub, so that when glibc supports the optimized tls call stub gcc
can generate code that assumes only r0, r12 and of course r3 are
changed on a __tls_get_addr call. When gcc expects __tls_get_addr
calls to preserve registers the call will be to __tls_get_addr_desc,
which will be translated by the linker to a call to __tls_get_addr_opt.

x86-64: Fix TLSDESC relaxation for x32
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required. Otherwise linker can’t safely perform
GDesc -> IE/LE optimization. X32 TLSDESC sequences can be:
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
...
67 ff 10 call *x@TLSCALL(%eax)
or the same sequence as LP64:
48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg
...
ff 10 call *foo@TLSCALL(%rax)
We need to support both sequences for x32. For both GDesc -> IE/LE
transitions,
67 ff 10 call *x@TLSCALL(%eax)
should relaxed to
0f 1f 00 nopl (%rax)
For GDesc -> LE transition,
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
should relaxed to
40 c7 c0 fc ff ff ff rex movl $x@tpoff, %reg
For GDesc -> IE transition,
40 8d 05 00 00 00 00 rex lea x@TLSDESC(%rip), %reg
should relaxed to
40 8b 05 00 00 00 00 rex movl x@gottpoff(%rip), %eax

Memory leaks and ineffective bounds checking in wasm_scan
It's always a bad idea to perform arithmetic on an unknown value read
from an object file before comparing against bounds. Code like the
following attempting to bounds check "len", a 64-bit value, isn't
effective because the pointer arithmetic ignores the high 32 bits when
compiled for a 32-bit host.
READ_LEB128 (len, p, end);
if (p + len < p || p + len > end)
goto error_return;
Instead, perform any arithmetic on known values where we don't need to
worry about overflows:
READ_LEB128 (len, p, end);
if (len > (size_t) (end - p))
goto error_return;
I'll note that this check does do things the right way:
READ_LEB128 (symcount, p, end);
/* Sanity check: each symbol has at least two bytes. */
if (symcount > payload_size / 2)
return FALSE;
"symcount * 2 > payload_size" would be wrong since the multiply could
overflow.
