re PR target/84335 (ICE on invalid code in copy_to_mode_reg, at explow.c:612)

	PR target/84335
	* config/i386/i386.c (ix86_init_mmx_sse_builtins): Pass
	OPTION_MASK_ISA_AES | OPTION_MASK_ISA_SSE2 instead of
	OPTION_MASK_ISA_AES as first argument to def_builtin_const
	for AES builtins.  Pass OPTION_MASK_ISA_PCLMUL | OPTION_MASK_ISA_SSE2
	instead of OPTION_MASK_ISA_PCLMUL as first argument to
	def_builtin_const for __builtin_ia32_pclmulqdq128 builtin.
	* config/i386/wmmintrin.h: If __SSE2__ is not defined, enable it
	temporarily for AES and PCLMUL builtins.

	* gcc.target/i386/pr84335.c: New test.
