Florian Hahn a60d0184bb [LCSSA] Provide option for caller to clean up unused PHIs. ... formLCSSAForInstructions is used by SCEVExpander, which tracks all inserted instructions including LCSSA phis using asserting value handles. This means cleanup needs to happen in the caller. Extend formLCSSAForInstructions to take an optional pointer to a vector. If this argument is non-nullptr, instead of directly deleting the phis, add them to the vector, so the caller can process them. This should address various PPC buildbot failures, including http://lab.llvm.org:8011/builders/clang-ppc64be-linux-lnt/builds/40567		2020-08-01 20:43:19 +01:00
