912eb1f7c1 Remove ResultsCursor::get_with_analysis. 
We can just call `ResultsCursor::state` and `ResultsCursor::analysis`
separately.

406c0b8ae4 Remove unnecessary mut. 
`mut_results` immediately below is the `&mut self` version, this one
should be `&self`.

0f12da17c0 Remove unused arguments from on_all_children_bits. 
`on_all_children_bits` has two arguments that are unused: `tcx` and
`body`. This was not detected by the compiler because it's a recursive
function.

This commit removes them, and removes lots of other arguments and fields
that are no longer necessary.

f450bf49c0 Use 'mir lifetime name more. 
Some types have a `body: &'mir Body<'tcx>` and some have `body: &'a
Body<'tcx>`. The former is more readable, so this commit converts some
fo the latter to the former.

e7781c75f8 Move has_rustc_mir_with. 
`lib.rs` is a strange place for it, and it's only used within
`rustc_peek.rs`, so it doesn't need to be `pub`.

7060fc8327 Replace no_ord_impl with orderable. 
Similar to the previous commit, this replaces `newtype_index`'s opt-out
`no_ord_impl` attribute with the opt-in `orderable` attribute.

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`.

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.
