[PATCH] D14598: Cleanup some -Wundef warnings in include/llvm/Support/MathExtras.h

Thanks! On a similar note, should the instances of `__GNUC__ >= 4` probably be changed to `LLVM_GNUC_PREREQ(4, 0, 0)`? Can be dealt with in a separate patch since I don't build under MSVC with the equivalent warning levels.
