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.

Remove on_all_drop_children_bits.

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

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.
