*	[ValueTracking] Teach isKnownNonZero about monotonically increasing PHIs	James Molloy	2015-09-29	1	-0/+49
	If a PHI starts at a non-negative constant, monotonically increases (only adds of a constant are supported at the moment) and that add does not wrap, then the PHI is known never to be zero. llvm-svn: 248796
