Adhemerval and Florian, apart from the discussion to remove or not
fenvinline.h altogether, could we push this commit? This header is
currently in a broken state and I'd like to fix it for the time being.

If you have any other suggestions / reservations about using
__builtin_popcount (__e) == 1, I'd be happy to consider and provide an
alternative patch if needed.

Thanks,
Matheus Castanho
