[PATCH 2/5 V1] RISC-V:Implement built-in instructions for Crypto extension

[shihua@iscas.ac.cn]

From: LiaoShihua <shihua@iscas.ac.cn>

gcc/ChangeLog:

        * config/riscv/riscv-builtins.cc (RISCV_FTYPE_NAME2): Defined new function prototypes.
        (RISCV_FTYPE_NAME3): Ditto.
        (AVAIL): Defined new riscv_builtin_avail for crypto extension.
        (RISCV_ATYPE_SI): Defined new argument type.
        (RISCV_ATYPE_DI): Ditto.
        (RISCV_FTYPE_ATYPES2): Defined new RISCV_FTYPE_ATYPESN
        (RISCV_FTYPE_ATYPES3): Ditto.
        * config/riscv/riscv-ftypes.def (1): Defined new prototypes for RISC-V built-in functions.
        (2): Ditto.
        (3): Ditto.
        * config/riscv/riscv-builtins-crypto.def: Defined new RISC-V built-in functions for crypto extension.
