Remove dead code in GVN: now that SimplifyInstruction is called systematically, CollapsePhi will always return null here. Note that CollapsePhi did an extra check, isSafeReplacement, which the SimplifyInstruction logic does not do. I think that check was bogus - I guess we will soon find out! (It was originally added in commit 41998 without a testcase). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119456 91177308-0d34-0410-b5e6-96231b3b80d8
