exp2f(x): compute the base 2 exponential of x
Accuracy: Peak error < 0.501 ulp; location of peak: -0.030110927.
Method: (equally-spaced tables)
Reduce x:
x = 2**k + y, for integer k and |y| <= 1/2.
Thus we have exp2f(x) = 2**k * exp2(y).
Reduce y:
y = i/TBLSIZE + z for integer i near y * TBLSIZE.
Thus we have exp2(y) = exp2(i/TBLSIZE) * exp2(z),
with |z| <= 2**-(TBLSIZE+1).
We compute exp2(i/TBLSIZE) via table lookup and exp2(z) via a
degree-4 minimax polynomial with maximum error under 1.4 * 2**-33.
Using double precision for everything except the reduction makes
roundoff error insignificant and simplifies the scaling step.
This method is due to Tang, but I do not use his suggested parameters:

We save and restore the floating-point environment to avoid raising
an inexact exception. We can get away with using fesetenv()
instead of feclearexcept()/feupdateenv() to restore the environment
because the only exception defined for rint() is overflow, and
rounding can't overflow as long as emax >= p.
The volatile keyword is needed below because clang incorrectly assumes
that rint won't raise any floating-point exceptions. Declaring ret volatile
is sufficient to trick the compiler into doing the right thing.
