*	[PowerPC] Fix a DAG replacement bug in PPCTargetLowering::DAGCombineExtBoolTrunc	Hal Finkel	2016-05-12	1	-0/+38
	While promoting nodes in PPCTargetLowering::DAGCombineExtBoolTrunc, it is possible for one of the nodes to be replaced by another. To make sure we do not visit the deleted nodes, and to make sure we visit the replacement nodes, use a list of HandleSDNodes to track the to-be-promoted nodes during the promotion process. The same fix has been applied to the analogous code in PPCTargetLowering::DAGCombineTruncBoolExt. Fixes PR26985. llvm-svn: 269272
