rustc: use LocalDefId instead of DefIndex where possible.
That is, wherever `DefIndex` always referred to a "def" in the local crate, I replaced it with `LocalDefId`.
While `LocalDefId` already existed, it wasn't used a lot, but I hope I'm on the right track.
Unresolved questions:
* [x] ~~should `LocalDefId` implement `rustc_index::Idx`?~~
* ~~this would get rid of a couple more `DefIndex` uses~~
* [x] ~~should `LocalDefId` be encoded/decoded as just a `DefIndex`?~~
* ~~right now it's a bit messy, `LocalDefId` encodes/decodes like `DefId`~~
* [x] ~~should `DefId::assert_local` be named something else, like `expect_local`?~~
A future PR should change `tcx.hir().local_def_id(...)` to return `LocalDefId` instead of `DefId`, as changing it in this PR would be too noisy.
