This patch adds isel support for STRICT_LRINT/LLRINT/LROUND/LLROUND.

It also adds test cases for f32 and f64 constrained intrinsics that
correspond to the intrinsics in float-intrinsics.ll and
double-intrinsics.ll. Support for promoting the integer argument of
STRICT_FPOWI was added.

I've skipped adding tests for f16 intrinsics, since we don't have libcalls
for them and we have inconsistent support for promoting them in LegalizeDAG.
This will need to be examined more closely.
