The code and checks have been updated here because internally to LLVM we're deleting and recreating these intrinsics; although it seems like it should be a no-op, the builder will eagerly try to make the new intrinsics tail calls, hence we get the `tail` prefix after the otherwise-opaque roundtrip.
