Fix a serious performance regression introduced by r108687 on linux: turning (fptrunc (sqrt (fpext x))) -> (sqrtf x) is great, but we have to delete the original sqrt as well. Not doing so causes us to do two sqrt's when building with -fmath-errno (the default on linux). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113260 91177308-0d34-0410-b5e6-96231b3b80d8
