Replace the existing `f16` test with the version that is uses for other architectures (typically as `half.ll`). This still covers the conversions from the existing test, but also adds checks for most simple ops. Additionally, rename `half-precision.ll` to `fp-intrinsics.ll` to keep the name similar to this test.

Replace the existing
f16test with the version that is uses for other architectures (typically ashalf.ll). This still covers the conversions from the existing test, but also adds checks for most simple ops.Additionally, rename
half-precision.lltofp-intrinsics.llto keep the name similar to this test.
