Max Kazantsev 55e622cae0 [SimplifyIndVars] Ignore dead users ... IndVarSimplify sometimes makes transforms basing on users that are trivially dead. In particular, if DCE wasn't run before it, there may be a dead `sext/zext` in loop that will trigger widening transforms, however it makes no sense to do it. This patch teaches IndVarsSimplify ignore the mist trivial cases of that. Differential Revision: https://reviews.llvm.org/D47974 Reviewed By: sanjoy llvm-svn: 334567		2018-06-13 02:25:32 +00:00
