Craig Topper 405f938399 [InstCombine] Make sure we preserve fast math flags when folding fp instructions into phi nodes

Summary: I noticed in the select folding code that we copied fast math flags, but did not do the same for the similar handling in phi nodes. This patch fixes that to do the same thing as select
