	* config/i386/sse.md (*mov<mode>_internal): Merge with
	*mov<mode>_internal_rex64.  Use x64 and nox64 isa attributes.
	Emit insn template depending on type attribute.  Use
	HAVE_AS_IX86_INTERUNIT_MOVQ to handle broken assemblers that require
	movd instead of movq mnemonic for interunit moves.  Rewrite mode
	attribute calculation.  Remove unit attribute calculation.
	Set prefix attribute to maybe_vex for sselog1 and ssemov types.
	Set prefix_data16 attribute for DImode ssemov types.
	Use Ym instead of y for SSE-MMX conversion alternatives.
	Reorder operand constraints.
