  Changed paths:

    M llvm/test/CodeGen/X86/is_fpclass.ll

  Log Message:
  -----------
  DAG: Lower single infinity is.fpclass tests to fcmp (#100380)

InstCombine also should have taken care of this, but this
should be helpful when the fcmp based lowering strategy tries
to combine multiple tests.
