re PR target/50310 (ICE: in gen_vcondv2div2df, at config/i386/sse.md:1435 with -O -ftree-vectorize and __builtin_isunordered()) 

2012-03-05  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/50310
	* config/rs6000/vector.md (vector_uneq<mode>): Add support for
	UNEQ, LTGT, ORDERED, and UNORDERED IEEE vector comparisons.
	(vector_ltgt<mode>): Likewise.
	(vector_ordered<mode>): Likewise.
	(vector_unordered<mode>): Likewise.
	* config/rs6000/rs6000.c (rs6000_emit_vector_compare_inner):
	Likewise.
