[PATCH] D74712: Remove *_finite libary support, following upstream

[Andy Kaylor via Phabricator via llvm-commits]

andrew.w.kaylor added a comment.

It's a little weird that we're still recognizing these as LibFuncs, but I guess that's necessary to keep the optimizations like constant folding working with them. I see that ConstantFolding already calls the non-finite-restricted versions of the functions when it's doing compile-time evaluation. It would be good to have a comment somewhere (probably in TargetLibraryInfo.cpp below the note about math-finite.h) explaining the handling of these functions.
