MIPS/GAS/testsuite: Implement individual MIPS16 ISA testing
Implement individual MIPS16 ISA GAS testing for the 32-bit and 64-bit variants of the base MIPS16 and the MIPS16e ISA each. gas/ * testsuite/gas/mips/mips.exp (run_dump_test_arch): Add `mips16e' and `mips16' prefixes. (run_list_test_arch): Likewise. Rename `mips16' architecture to `mips16-32'. Add `mips16-64', `mips16e-32' and `mips16e-64' architectures. Update `rol64', `mips16e', `elf${el}-rel2' and `elf-rel4' test invocations accordingly. * testsuite/gas/mips/mips16e@branch-swap-3.d: New test. * testsuite/gas/mips/mips16e@branch-swap-4.d: New test. * testsuite/gas/mips/mips16e@loc-swap-dis.d: New test. * testsuite/gas/mips/mips16e@loc-swap.d: New test.
