PPC64: Add libmvec SIMD single-precision natural exponent function [BZ #24209]
Passes all tests.
Based off the ./sysdeps/ieee754/dbl-64/e_exp.c implementation,
and thus provides identical results.
Unlike other libmvec functions, this sets the underflow and overflow bits.
The caller can check these flags, and possibly re-run the calculations with
scalar expf to figure out what is causing the overflow or underflow.
Suprisingly the special-case path performs as well as the normal path.
(both of which are vectorized)
