re PR target/65569 (Fix for PR target/65240 causes a regression in building Spec for power4/power5/power6) 

2015-03-25  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR target/65569
	* config/rs6000/rs6000.md (extenddftf2_fprs): On VSX systems use
	XXLXOR to create 0.0.  On pre-VSX systems make sure the constant
	0.0 is correctly setup.
	(extenddftf2_internal): Likewise.
