*	Bugfix: SCEV incorrectly marks certain add recurrences as nsw	Sanjoy Das	2015-02-09	1	-0/+26
	When creating a scev for sext({X,+,Y}), scev checks if the expression is equivalent to {sext X,+,zext Y}. If it can prove that, it also tags the original {X,+,Y} as <nsw>, which is not correct. In the test case I run `-scalar-evolution` twice because the bug manifests only once SCEV has run through and seen the `sext` expressions (and then does a in-place mutation on {X,+,Y}).
