MIPS: Verify the ISA mode and alignment of branch and jump targets
Verify that the ISA mode of branch targets is the same as the referring
relocation, so that an attempt to produce a branch between instructions
encoded in different ISA modes each causes an error rather than silently
producing non-functional code. Make sure that no symbol or addend bits
are silently truncated: terminate with an error if the relocation value
calculated cannot be encoded in the relocatable field of a branch; for
REL targets also applying to any intermediate addend.
Also make jump target's alignment verification consistent with that for
branches.
This change will require an update to some obscure handcoded assembly
sources which make branches to labels placed at data objects, however
for microMIPS code only. These labels will have to be updated with the
`.insn' directive for containing code to assemble and link successfully.
Such code is broken as any such labels have always been required by the
microMIPS architecture specification[1][2] to be annotated this way for
correct interpretation, and with our old code missing `.insn' directives
caused labels to present different semantics depending on whether they
were referred with branch (ISA bit ignored) or other relocations (ISA
bit respected).
Enforcing these checks however will ensure errors in building software,
like mixed regular MIPS and microMIPS code links with branches between,
will be diagnosed at the build time rather than causing odd run-time
errors such as intermittent crashes. It will also let cross-mode BAL
instructions be converted to JALX instructions, with a separate change.

MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement
Similarly to commit 86b24e15c45b ("MIPS/LD/testsuite: Correct
comm-data.exp test ABI/emul/endian arrangement") update the mips-elf.exp
test script to:
- correctly select emulations for targets using non-traditional MIPS
emulations,
- correctly select ABIs for targets that do not support all of them,
- use the default endianness selection where possible to benefit targets
that support only one,
- simplify test invocation by providing ABI-specific `run_dump_test'
wrappers, specifically `run_dump_test_o32', `run_dump_test_n32',
`run_dump_test_n64' and `run_dump_test_eabi', which remove the need to
use conditionals across the Expect script or to repeat ABI-specific
GAS and LD flags with each invocation,
removing numerous test failures for `mips-sgi-irix6', `mips64-openbsd',
`mips64el-openbsd' and `mips64el-ps2-elf' targets and broadening
coverage for several MIPS targets.
There are some new failures for the `mips64el-ps2-elf' target with tests
that were not previously run for that target:
FAIL: MIPS16 link branch to absolute expression (n32)
FAIL: MIPS16 link branch to absolute expression 1 (n32)
FAIL: MIPS16 link branch to absolute expression 2 (n32)
FAIL: microMIPS link branch to absolute expression (n32)
FAIL: MIPS ELF got reloc n32
FAIL: MIPS ELF xgot reloc n32
FAIL: undefined weak symbol overflow (n32)
FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs n32
FAIL: ld-mips-elf/attr-gnu-4-0-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-1-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-2-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-3-n32-ph
FAIL: MIPSr6 JALR reloc unaligned/cross-mode link test (n32)
which are mostly due to dump discrepancies caused by mapping differences
coming from the default linker scripts used by these test cases, or
sometimes because of the specific MIPS processor architecture recorded
in the ELF file taking precedence over the general MIPS ISA level also
recorded. Finally, the R_MIPS16_HI16/R_MIPS16_LO16 relocation test
failure is a preexisting issue with the IRIX style emulation.
These failures will have to be addressed separately.

MIPS: Verify the ISA mode and alignment of branch and jump targets
Verify that the ISA mode of branch targets is the same as the referring
relocation, so that an attempt to produce a branch between instructions
encoded in different ISA modes each causes an error rather than silently
producing non-functional code. Make sure that no symbol or addend bits
are silently truncated: terminate with an error if the relocation value
calculated cannot be encoded in the relocatable field of a branch; for
REL targets also applying to any intermediate addend.
Also make jump target's alignment verification consistent with that for
branches.
This change will require an update to some obscure handcoded assembly
sources which make branches to labels placed at data objects, however
for microMIPS code only. These labels will have to be updated with the
`.insn' directive for containing code to assemble and link successfully.
Such code is broken as any such labels have always been required by the
microMIPS architecture specification[1][2] to be annotated this way for
correct interpretation, and with our old code missing `.insn' directives
caused labels to present different semantics depending on whether they
were referred with branch (ISA bit ignored) or other relocations (ISA
bit respected).
Enforcing these checks however will ensure errors in building software,
like mixed regular MIPS and microMIPS code links with branches between,
will be diagnosed at the build time rather than causing odd run-time
errors such as intermittent crashes. It will also let cross-mode BAL
instructions be converted to JALX instructions, with a separate change.

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.
