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.
- A new vectorization library argument is added to -fveclib: -fveclib=SLEEF.

Trigonometry functions that are vectorized by sleef:
acos
asin
atan
atanh
cos
cosh
exp
exp2
exp10
lgamma
log10
log2
log
sin
sinh
sqrt
tan
tanh
tgamma
