[AArch64][11/14] Re-layout SIMD builtin types on builtin expansion

	* config/aarch64/aarch64.c (aarch64_option_valid_attribute_p):
	Initialize simd builtins if TARGET_SIMD.
	* config/aarch64/aarch64-builtins.c (aarch64_init_simd_builtins):
	Make sure that the builtins are initialized only once no matter how
	many times the function is called.
	(aarch64_init_builtins): Unconditionally initialize crc builtins.
	(aarch64_relayout_simd_param): New function.
	(aarch64_simd_expand_args): Use above during argument expansion.
	* config/aarch64/aarch64-c.c (aarch64_pragma_target_parse): Initialize
	simd builtins if TARGET_SIMD.
	* config/aarch64/aarch64-protos.h (aarch64_init_simd_builtins): New
	prototype.
	(aarch64_relayout_simd_types): Likewise.

	* gcc.target/aarch64/target_attr_crypto_ice_1.c: New test.
