*	[SCEV] Make getPostIncExpr guaranteed to return AddRec	Max Kazantsev	2018-02-12	1	-0/+44
	The current implementation of `getPostIncExpr` invokes `getAddExpr` for two recurrencies and expects that it always returns it a recurrency. But this is not guaranteed to happen if we have reached max recursion depth or refused to make SCEV simplification for other reasons. This patch changes its implementation so that now it always returns SCEVAddRec without relying on `getAddExpr`. Differential Revision: https://reviews.llvm.org/D42953 llvm-svn: 324866
