John Stiles 115645ee9b Evaluate various single-argument float intrinsics at compile time.
This CL only handles a subset of our intrinsics. In particular, it
avoids changing the behavior of `sqrt` as many of our tests use sqrt as
an optimization barrier.

The transcendental test inputs are intentionally kept very simple to
avoid putting numbers in the test outputs which could round differently
on various platforms and cause Housekeeper to complain.
