This changeset is modeled after Intel's submission for SVML. It enables trigonometry functions vectorization via SLEEF: http://sleef.org/.
- A new vectorization library enum is added to TargetLibraryInfo.h: SLEEF.
- A new option is added to TargetLibraryInfoImpl - ClVectorLibrary: SLEEF.
- A comprehensive test case is included in this changeset.
- In a separate changeset (for clang), a new vectorization library argument is added to -fveclib: -fveclib=SLEEF.
Trigonometry functions that are vectorized by sleef:
