[APFloat] Rename isIEEENormal => isNormal and remove old isNormal method.

The old isNormal is already functionally replaced by the method isFiniteNonZero
in r184350 and all references to said method were replaced in LLVM/clang in
r184356/134366.

Use that in llvm-ar.cpp to replace a use of sys::PathWithStatus.
