6e5e0daff2 Changes the type mir::Mir into mir::Body 
The commit should have changed comments as well.
At the time of writting, it passes the tidy and check tool.

Revisions asked by eddyb :
- Renamed of all the occurences of {visit/super}_mir
- Renamed test structures `CachedMir` to `Cached`

Fixing the missing import on `AggregateKind`

257eaf523f Introduce InternedString::intern. 
`InternedString::intern(x)` is preferable to
`Symbol::intern(x).as_interned_str()`, because the former involves one
call to `with_interner` while the latter involves two.

The case within InternedString::decode() is particularly hot, and this
change reduces the number of `with_interner` calls by up to 13%.

c1d2d83ca3 Auto merge of #58754 - ljedrz:I_hate_NodeIds, r=Zoxc 
Remove NodeId from more HIR nodes

The next iteration of HirIdification (#57578).

Removes `NodeId` from:

- [x] `Stmt`
- [x] `Local`
- [x] `Field`
- [x] `AnonConst`
- [x] `TraitItem`
- [x] `ImplItem`
- [x] `TypeBinding`
- [x] `Arg`
- [x] `TraitRef`
- [x] `VisibilityKind`

It will most probably break clippy again; I'd appreciate a **delegate** again if/when it is good to go so I can attach a clippy fix later.

these, they can be removed.

Refactor and add PlaceContext::AscribeUserTy. 
This commit refactors `PlaceContext` to split it into four different
smaller enums based on if the context represents a mutating use,
non-mutating use, maybe-mutating use or a non-use (this is based on the
recommendation from @oli-obk on Zulip[1]).

This commit then introduces a `PlaceContext::AscribeUserTy` variant.
`StatementKind::AscribeUserTy` is now correctly mapped to
`PlaceContext::AscribeUserTy` instead of `PlaceContext::Validate`.
`PlaceContext::AscribeUserTy` can also now be correctly categorized as a
non-use which fixes an issue with constant promotion in statics after a
cast introduces a `AscribeUserTy` statement.
