[PATCH] RISC-V: Add "OP_P" to .insn named opcodes

[Tsukasa OI <research_trasio@irq.a4lg.com>]

From: Tsukasa OI <research_trasio@irq.a4lg.com>

This commit adds "OP_P" (OP-P: packed SIMD instruction opcode intended for
the 'P' extension but its use is first approved for the vector cryptography
specification) to .insn opcode name list.  Although vector / packed SIMD
instruction encodings are not implemented in `.insn' directive, it will help
future implementation of custom vector / packed SIMD `.insn'.

gas/ChangeLog:

	* config/tc-riscv.c (opcode_name_list): Add "OP_P".
	* testsuite/gas/riscv/insn.s: Add "OP_P" vector crypto testcase.
	* testsuite/gas/riscv/insn.d: Likewise.
	* testsuite/gas/riscv/insn-na.d: Likewise.
	* testsuite/gas/riscv/insn-dwarf.d: Reflect insn.s update.
