3abf975826 MIPS/binutils/testsuite: Correct mips.exp test ABI/emul/endian arrangement
The binutils testsuite supports involving LD in processing test cases
and with the MIPS target that has the same issues the LD testsuite does.

So to support LD in the MIPS part of the binutils testsuite similarly
to commit 86b24e15c45b ("MIPS/LD/testsuite: Correct comm-data.exp test
ABI/emul/endian arrangement") update the mips.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' and
  `run_dump_test_n64', which remove the need to use conditionals across
  the Expect script or to repeat ABI-specific GAS and LD flags with each
  invocation,

borrowing changes from commit 78da84f99405 ("MIPS/LD/testsuite: Correct
mips-elf.exp test ABI/emul/endian arrangement").

As a side effect this disables o32 ABI testing for targets that are not
supposed to support them and do not with LD, but still have such support
with BFD and GAS due to our inflexibility in configuration.  Ultimately
we ought to support having o32 completely disabled.

	(run_dump_test_o32, run_dump_test_n32, run_dump_test_n64): New

	Replace `run_dump_test' calls where applicable throughout with
	`run_dump_test_o32', `run_dump_test_n32' and `run_dump_test_n64'
	as appropriate.  Use `noarch' for tests that require their own
	architecture setting.

a4ddc54ec1 MIPS16/opcodes: Keep the LSB of PC-relative offsets in disassembly
Correct the disassembly of the PC-relative immediate argument of the
MIPS16 synthetic LA, LW, DLA and LD instructions and do not mask the
LSB, which in this case is a part of the data address rather than the
ISA bit and has to be fully presented.

	opcodes/
	* mips-dis.c (print_insn_arg): Only clear the ISA bit for jumps
	and branches and not synthetic data instructions.

	binutils/
	* testsuite/binutils-all/mips/mips16-undecoded.d: Adjust the
	disassembly of PC-relative LA and LW synthetic instructions.

   0:	f008 0231 	addiu	v0,sp,16401
   4:	f520 3260 	sll	v0,v1,20
