This changeset adds the required Builtins for enabling AArch64 vectorization of libm trigonometry functions via SLEEF: http://sleef.org/.

- A new argument is added to -fveclib=<X>: SLEEF.
- A number of Builtins that were previously unimplemented are now enabled.

This changeset depends on https://reviews.llvm.org/D53927.

List of SLEEF vectorized trigonometry functions:

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