This reverts D123693 <https://reviews.llvm.org/D123693> except that some of the tests added by that patch
are adapted instead of being removed.

The functionality of allowing unsupported intrinsics to select has been
superseded by D139000 <https://reviews.llvm.org/D139000> "Remove function with incompatible features".
