8ff624a9f2 Clean up rustc_*/Cargo.toml. 
- Sort dependencies and features sections.
- Add `tidy` markers to the sorted sections so they stay sorted.
- Remove empty `[lib`] sections.
- Remove "See more keys..." comments.

Excluded files:
- rustc_codegen_{cranelift,gcc}, because they're external.
- rustc_lexer, because it has external use.
- stable_mir, because it has external use.

cd674d6179 Auto merge of #116300 - cjgillot:split-move, r=petrochenkov 
Separate move path tracking between borrowck and drop elaboration.

The primary goal of this PR is to skip creating a `MovePathIndex` for path that do not need dropping in drop elaboration.

The 2 first commits are cleanups.

The next 2 commits displace `move` errors from move-path builder to borrowck. Move-path builder keeps the same logic, but does not carry error information any more.

The remaining commits allow to filter `MovePathIndex` creation according to types. This is used in drop elaboration, to avoid computing dataflow for paths that do not need dropping.

547af00019 Remove on_all_drop_children_bits. 
As drop elaboration only tracks places that need dropping, is has become
equivalent to `on_all_children_bits`.

That information is redundant. Is the path is terminal, `first_child` will
already be `None`.

Rollup merge of #115770 - ouz-a:match_elem_builder, r=lcnr 
Match on elem first while building move paths

While working on https://github.com/rust-lang/rust/pull/115025 `@lcnr` and I observed "move_paths_for" function matched on the `Ty` instead of `Projection` which seems flawed as it's the `Projection`s that cause the problem not the type.
