(MIPS operand specifier comments): Remove 'm', add 'U' and
'J', and update the meaning of 'B' so that it's more general.
* mips.h (INSN_ISA1, INSN_ISA2, INSN_ISA3, INSN_ISA4,
INSN_ISA5): Renumber, redefine to mean the ISA at which the
instruction was added.
(INSN_ISA32): New constant.
(INSN_4650, INSN_4010, INSN_4100, INSN_3900, INSN_GP32):
Renumber to avoid new and/or renumbered INSN_* constants.
(INSN_MIPS32): Delete.
(ISA_UNKNOWN): New constant to indicate unknown ISA.
(ISA_MIPS1, ISA_MIPS2, ISA_MIPS3, ISA_MIPS4, ISA_MIPS5,
ISA_MIPS32): New constants, defined to be the mask of INSN_*
constants available at that ISA level.
(CPU_UNKNOWN): New constant to indicate unknown CPU.
(CPU_4K, CPU_MIPS32_4K): Rename the former to the latter,
define it with a unique value.
(OPCODE_IS_MEMBER): Update for new ISA membership-related
constant meanings.
