  Changed paths:
    M llvm/lib/Analysis/ConstantFolding.cpp

  Log Message:
  -----------
  [ConstantFold] Special case log1p +/-0.0

C's Annex F specifies that log1p +/-0.0 returns the input value;
however, this behavior is optional and host C libraries may behave
differently. This change applies the Annex F behavior to constant
folding by LLVM.
