Now the code works correctly with -disable-fp-elim.

However, it fails without it now: when I compile the exception handling runtime
(that contains a function calling _Unwind_RaiseException) without
-disable-fp-elim, _Unwind_RaiseException returns an error code of 5 (which I
think means END_OF_STACK). 

It does not matter whether the user code is compiled with -disable-fp-elim or
not. This case worked correctly prior to the fix.
