Add load-link, store-conditional paired EVA instructions
Add paired load-link and store-conditional instructions to the
EVA ASE for MIPS32R6[1]. These instructions are optional within
the EVA ASE. Their presence is indicated by the XNP bit in the
Config5 register.

gas/
* config/tc-mips.c (mips_set_ase): Handle ASE_EVA_R6.
(macro) <M_LLWPE_AB, M_SCWPE_AB>: New cases.
(mips_after_parse_args): Translate EVA to EVA_R6.
* testsuite/gas/mips/ase-errors-1.s: Add new instructions.
* testsuite/gas/mips/eva.s: Likewise.
* testsuite/gas/mips/ase-errors-1.l: Check errors for
new instructions.
* testsuite/gas/mips/mipsr6@eva.d: Check new test cases.
include/
* opcode/mips.h (ASE_EVA_R6): New macro.
(M_LLWPE_AB, M_SCWPE_AB): New enum values.
opcodes/
* mips-dis.c (mips_calculate_combination_ases): Add ISA
argument and set ASE_EVA_R6 appropriately.
(set_default_mips_dis_options): Pass ISA to above.
(parse_mips_dis_option): Likewise.
* mips-opc.c (EVAR6): New macro.
(mips_builtin_opcodes): Add llwpe, scwpe.
