Respin sparc pixel-compare patterns using iterators.

	* config/sparc/sparc.md (UNSPEC_FCMPLE, UNSPEC_FCMPNE,
	UNSPEC_FCMPGT, UNSPEC_FCMPEQ): Delete and reduce to...
	(UNSPEC_FCMP): New unspec.
	(gcond): New code iterator.
	(gcond_name): New code attr.
	(GCM): New mode iterator.
	(gcm_name): New mode attr.
	(fcmp{le,ne,gt,eq}{16,32}_vis): Reimplement using iterators.
