Kevin Enderby d49b2a7a9d Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses a ...

symbol from an assignment.  In this case the symbol did not have a fragment so
MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.
