Vector expf for x86_64 and tests.
Here is implementation of vectorized expf containing SSE, AVX,
AVX2 and AVX512 versions according to Vector ABI
<https://groups.google.com/forum/#!topic/x86-64-abi/LmppCfN1rZ4>.
* sysdeps/unix/sysv/linux/x86_64/libmvec.abilist: New symbols added.
* sysdeps/x86/fpu/bits/math-vector.h: Added SIMD declaration and asm
redirections for expf.
