There was a problem hiding this comment.
Note: I did not remove #[inline]. It's just a quirk of the diff that it looks that way.

This function returned a fake `DefIndex`, with no indication that it was fake, when it was provided with a `FakeDefId::Fake`. Every use of the function uses the returned `DefIndex` in a call to `tcx.local_def_id_to_hir_id()`, which I'm pretty sure would panic if it were given a fake `DefIndex`. I removed the function and replaced all calls to it with a call to `expect_real()` followed by `DefId::expect_local()` (that's a function on the *real* `DefId`).
Now, in the case that the function is not inlined, the panic location will be the caller's location, which is more helpful since the panic is not `expect_real()`'s fault.
