	Modify Z->r bswapdi splitter to use dest in place of scratch.
	In r->Z and Z->r bswapdi splitter rename word_high, word_low
	to word1, word2 and rearrange logic to suit.
	(bswapdi2_64bit): Remove early clobber on Z->r alternative.
	(bswapdi2_ldbrx): Likewise.  Remove '??' on r->r.
	(bswapdi2_32bit): Remove early clobber on Z->r alternative.
	Add one '?' on r->r.  Modify Z->r splitter to avoid need for
	early clobber.
