Your test fails because you aren't actually using `core.bitop`.
Intrinsics are detected based on fully qualified names. As soon
as you copy `bsf()` and `bsr()` outside of `core.bitop`, the
FQN changes and they're not intrinsics anymore.
Does DMD overrides bodies for bsf and bsr? It would be surprised
to me.
