	* config/i386/i386.c (ix86_legitimate_combined_insn): If for
	!TARGET_AVX there is misaligned MEM operand with vector mode
	and get_attr_ssememalign is 0, return false.
	(ix86_expand_special_args_builtin): Add get_pointer_alignment
	computed alignment and for non-temporal loads/stores also
	at least GET_MODE_ALIGNMENT as MEM_ALIGN.
	* config/i386/sse.md
