indvars cruft: don't replace phi nodes for no reason. Don't replace a phi with an identical phi. This was done long ago to "preserve" IVUsers analysis. The code has already called SE->forgetValue(PN) so I see no purpose in creating a new value for the phi. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237587 91177308-0d34-0410-b5e6-96231b3b80d8
