opcodes/
* mips-opc.c (CP): New macro.
(mips_builtin_opcodes): Mark c0, c2 and c3 as CP. Add Octeon to the
membership of di, dmfc0, dmtc0, ei, mfc0 and mtc0. Add dmfc2 and
dmtc2 Octeon instructions.
gas/
* config/tc-mips.c (NO_ISA_COP): New macro.
(COP_INSN): New macro.
(is_opcode_valid): Use them.
(macro) <ld_st>: Use them. Don't accept coprocessor load store
insns based on the ISA if CPU is NO_ISA_COP.
<copz>: Likewise for coprocessor operations.
