  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/FastISel.cpp
    R llvm/test/CodeGen/X86/fast-isel-fneg-kill.ll
    M llvm/test/CodeGen/X86/fast-isel-fneg.ll

  Log Message:
  -----------
  [FastISel] Don't transform FSUB(-0, X) -> FNEG(X) in FastISel

This corresponds with the SelectionDAGISel change in D84056.

Also, rename some poorly named tests in CodeGen/X86/fast-isel-fneg.ll with NFC.
