This patch fixes a bug in GAS where the assembler enters a tight loop
when attempting to resolve recursively-defined symbols, e.g. when
trying to assemble "a=a".
This is a regression introduced between binutils 2.32 and 2.33,
by commit 1903f1385b
* symbols.c (struct local_symbol): Update comment.
(resolve_symbol_value): For resolved symbols equated to other
symbols, verify that the referenced symbol is not a local_symbol
before accessing sy_value. Don't leave symbol loops during

The 64-bit version of binutils got support for the PE COFF BIG OBJ format a
couple of years ago. The BIG OBJ format is a slightly different COFF format
which extends the size of the number of section field in the header from a
uint16_t to a uint32_t and so greatly increases the number of sections allowed.
However the 32-bit version of bfd never got support for this. The GHC Haskell
compiler generates a great deal of symbols due to it's use of
-ffunction-sections and -fdata-sections.
This meant that we could not build the 32-bit version of the GHC Compiler for
many releases now as binutils didn't have this support.
This patch adds the support to the 32-bit port of binutils as well and also does
come cleanup in the code.

The check in bfd_get_full_section_contents is trying to check that we don't
allocate more space for a section than the size of the section is on disk.
Previously we excluded linker created sections since they didn't have a size on
disk. However we also need to exclude sections with no content as well such as
the BSS section. Space for these would not have been allocated by the assembler
and so the check would incorrectly fail.

This patch implements the TSB instructions:
https://developer.arm.com/docs/ddi0596/f/base-instructions-alphabetic-order/
tsb-csync-trace-synchronization-barrier
Since TSB and PSB both use the same (and only) argument "CSYNC", this patch
reuses it for TSB. However, the same argument would imply different value
for CRm:Op2 which are anyway fixed values, so I have diverted the
inserter/extracter function to dummy versions instead of the "hint" version.
The operand checker part still uses the existing infratructure for
AARCH64_OPND_BARRIER_PSB to make sure the operand is parsed correctly.

For one, the actual error is weird:
./ld-new: target elf64-x86-64 not found
failed with: <./ld-new: target elf64-x86-64 not found>, no expected output
FAIL: ld-ifunc/ifunc-10-x86-64
although ld -V does report the elf_x86_64 emulation as supported:
$ ./ld/ld-new -V
GNU ld (GNU Binutils) 2.34.50.20200328
Supported emulations:
elf_x86_64_sol2
elf_x86_64
[...]
When using ld -m elf_x86_64_sol2 instead, one of the testcases links
successfully.
However, there's no point in pursuing this: Solaris does not support
ifunc, as can be seen in <sys/elf.h>:
/*
* GNU/Linux specific symbol type not used by Solaris
*/
#define STT_GNU_IFUNC 10
and never will, given that it has symbol capabilities as solution to
effectively the same problem:
http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/
Therefore this patch disables ifunc testing on Solaris completely by
removing Solaris from binutils/testsuite/lib/binutils-common.exp
(supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is
in the OS-specific range and conflicts with
#define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */
While the comment suggests this might be relocatable without too much
problems, the description of mbind (no formal spec AFAICS, just the
comment in the binutils patch submission) strongly suggests that this
isn't relevant to Solaris at all.
Indirectly, clearing supports_gnu_osabi on Solaris disables
supports_gnu_unique. Again, Solaris <sys/elf.h> has
/*
* GNU/Linux specific binding not used by Solaris
*/
#define STB_GNU_UNIQUE 10
so this seems the right thing to do.
Afterwards, one can remove the explicit mentions of *-*-solaris2* in
quite a number of (but not all) the ld-ifunc dump file notarget lists.
There's one fallout, though: two gas tests now XPASS because they are
xfail'ed for !supports_gnu_osabi:
XPASS: mbind sections 12
XPASS: mbind section contents 16
XPASS: mbind sections 16
XPASS: mbind section contents 16
To fix that, I've changed
#xfail: ![supports_gnu_osabi]
to notarget.

Since https://sourceware.org/ml/binutils/2019-03/msg00163.html, gas
doesn't emit R_X86_64_PLT32 as branch marker on Solaris. Since the
testsuite lacks a way to preprocess dump files, adjusted copies of the
affected dumps are now used on Solaris. Unfortunately, those dumps
weren't adapted when the original testcases were changed or other
testcases started to differ between non-Solaris and Solaris targets.
The following patch fixes that, re-syncing the affected dump files or
creating new Solaris-specific ones.
Tested on i386-pc-solaris2.11, x86_64-pc-solaris2.11,
x86_64-pc-linux-gnu, and i686-pc-linux-gnu.

As explained in the PR, the addition of MVE makes the parser strip 't' and 'e'
as suffixes when MVE is enabled. This leads to vadd and vsub in it blocks with
lt and le conditions to be initially parsed as vaddl and vsubl. This means the
operand parsing for these must allow for the same operands as the scalar vadd
and vsub. I had forgotten to do this and this patch remedies that oversight.

These all follow an almost common pattern, again with the exception of
being commutative, which can be easily taken care of.
Note that, as an intended side effect (and in fact one of the reason to
introduce templates), AVX long-form pseudo-ops get introduced alongside
the already existing AVX512 ones.
Fixes a fail on hppa64-hp-hpux, where anything in the first column is
a label.
