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.

PowerPC64 __tls_get_addr_desc
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.
