Don't do the X * 0.0 -> 0.0 transformation in instcombine, because instcombine doesn't know when it's safe. To partially compensate for this, introduce new code to do this transformation in dagcombine, which can use UnsafeFPMath. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72872 91177308-0d34-0410-b5e6-96231b3b80d8
