[AArch64] Fix FAIL: gcc.target/aarch64/target_attr_crypto_ice_1.c (internal compiler error)

	* config/aarch64/aarch64.c (aarch64_set_current_function):
	Re-layout any vector parameters have non-simd layout.
	* config/aarch64/aarch64-builtins.c (aarch64_relayout_simd_param):
	Delete.
	(aarch64_simd_expand_args): Delete call to the above.

	* gcc.target/aarch64/target_attr_crypto_ice_2.c: New test.
