[PATCH] D53927: [AArch64] Enable trigonometry libm vectorized functions via SLEEF

[Stefan Teleman via Phabricator via llvm-commits]

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:

acos
asin
atan
atanh
cos
cosh
exp
exp2
exp10
lgamma
log10
log2
log
sin
sinh
sqrt
tan
tanh
tgamma
