• GAS: Add OP_V to .insn directive

Feature Description

OP-P (0x77) is an opcode originally intended for packed SIMD instructions (but its first use is approved for the vector cryptography extensions).

It adds OP_P to named constants of .insn directive (note that replacing - with _ is standard on GNU Binutils' .insn directive).

Although vector / packed SIMD instruction encodings are not implemented in .insn directive, it will help future implementation of custom vector / packed SIMD .insn.
