Sanjay Patel 28650b8ec2 InstCombine: fsub nsz 0, X ==> fsub nsz -0.0, X ... Some day the backend may handle instruction-level fast math flags and make this transform unnecessary, but it's still better practice to use the canonical representation of fneg when possible (use a -0.0). This is a partial fix for PR20870 ( http://llvm.org/bugs/show_bug.cgi?id=20870 ). See also http://reviews.llvm.org/D6723.
