Remove lie (in a comment) about conversion between 80 bit ot 64 bit reals,
...
since we set up the fpu to do all calculations in 64 bit mode at this time.

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).

Major Bogon: change %ebp to %esp, as I don't set up a stack frame.
