[PATCH] LoongArch: Control all __crc* __crcc* builtin functions with macro __loongarch64.

[Lulu Cheng]

LoongArch 32-bit instruction set does not support crc* and crcc* instructions.

gcc/ChangeLog:

        * config/loongarch/larchintrin.h (__crc_w_b_w): Add macros for control.
        (__crc_w_h_w): Likewise.
        (__crc_w_w_w): Likewise.
        (__crcc_w_b_w): Likewise.
        (__crcc_w_h_w): Likewise.
        (__crcc_w_w_w): Likewise.
        * config/loongarch/loongarch.md: Add condition TARGET_64BIT
        to loongarch_crc_* loongarch_crcc_* instruction template.
