lib: Add halffloat implementation
Probe for and make an API available for tests to use f16c intrinsics to
generate needed fp16 pixel data.
Also import a pure c fp32 <-> fp16 conversion implementation from Mesa
18.3.4, which will act as a fallback when f16c is unavailable.
rfc2:
- Change API to reduce number of function calls (Maarten)
v1:
- Move pragma so AVX code isn't emitted for fallbacks (Ville)
- Change edx to ecx (Ville)
