Chris Lattner 979ed44feb 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).
