I moved the existing (misplaced) test files:
59f3b3d7963b93 <https://reviews.llvm.org/rG59f3b3d7963b933451dcd7516dc3c7135d3c1258>
...so this will need another update. Also, see my suggestion to add test comments, so the current behavior is explained.

There's an open question about what to do with denormals. We recently added denorm-attribute-aware folding with:
D116952 <https://reviews.llvm.org/D116952>
D128647 <https://reviews.llvm.org/D128647>
...and we mentioned that it is a work-in-progress to get consistent behavior for intrinsics and libcalls. Exclude denorm inputs in this patch?
