Sjoerd Meijer 7eb70158e4 [IndVarSimplify][SimplifyIndVar] Move WidenIV to Utils/SimplifyIndVar. NFCI. ... This moves WidenIV from IndVarSimplify to Utils/SimplifyIndVar so that we have createWideIV available as a generic helper utility. I.e., this is not only useful in IndVarSimplify, but could be useful for loop transformations. For example, motivation for this refactoring is the loop flatten transformation: if induction variables in a loop nest can be widened, we can avoid having to perform certain overflow checks, enabling this transformation.
