Rollup merge of #133326 - nnethercote:rm-DefinitelyInitializedPlaces, r=cjgillot
Remove the `DefinitelyInitializedPlaces` analysis. Its only use is in the `tests/ui/mir-dataflow/def_inits-1.rs` where it is tested via `rustc_peek_definite_init`. Also, it's probably buggy. It's supposed to be the inverse of `MaybeUninitializedPlaces`, and it mostly is, except that `apply_terminator_effect` is a little different, and `apply_switch_int_edge_effects` is missing. Unlike `MaybeUninitializedPlaces`, which is used extensively in borrow checking, any bugs in `DefinitelyInitializedPlaces` are easy to overlook because it is only used in one small test. This commit removes the analysis. It also removes `rustc_peek_definite_init`, `Dual` and `MeetSemiLattice`, all of which are no longer needed. r? ``@cjgillot``
