Fix from Bruce Evans. Commited to FreeBSD earlier this month, but was
...
never forwarded to me :-(.
> Clean up the FP stack before returning. The i387 exp() leaked an FP

Use setne instead of setnel, new versions of gas balk at the bad mnemonic.

I'm only doing this for consistancy --- someone really needs to measure

The fyl2xp1 instruction has a limited range:
...
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
so we can't use it.
Also, I'm not sure fyl2xp1's extra precision will
matter once the result is converted from extended
real (80 bits) back to double real (64 bits).
