[PATCH] D79956: [InstCombine] Teach PromoteCastOfAllocation to not insert a bitcast into the middle of a group of allocas

[Craig Topper via Phabricator via llvm-commits]

FWIW, there's another place in InstCombine that does something like this,  simplifyAllocaArraySize in InstCombineLoadStoreAlloca.cpp  So I thought maybe this was desired behavior.
