Cycles: fix accuracy issues in fast_sin/fast_cos/fast_sincos
Most of these originate from OIIO of about 10 years ago. Integrate
the upstream fix from OIIO:
https://github.com/AcademySoftwareFoundation/OpenImageIO/commit/88feb65fc992
Cover them with unit tests. Before the fix, fast_sinf(1.57085085f)
was returning 0.0 instead of 1.0 as expected.
Revert previous hair workaround (a16879a5f0)
