Rewrite dead-code pass to avoid fetching HIR.

This allows to get a more uniform handling of spans, and to simplify the grouping of diagnostics for variants and fields.

3164c2aa15 Make logging for drop-tracking easier to read. 
Some of these are a little questionable because the output is so much longer, but I would really love to keep the bit that adds the pretty-printed expression to the generated CFG .dot file.

Before:
```
DEBUG rustc_typeck::check::generator_interior::drop_ranges::record_consumed_borrow consume PlaceWithHirId { hir_id: HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 15 }, place: Place { base_ty: impl std::future::Future<Output = ()>, base: Rvalue, projections: [] } }; diag_expr_id=HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 15 }, using parent expr HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 49 }
```

After:
```
DEBUG rustc_typeck::check::generator_interior::drop_ranges::record_consumed_borrow consume PlaceWithHirId { hir_id: HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 15 }, place: Place { base_ty: impl std::future::Future<Output = ()>, base: Rvalue, projections: [] } }; diag_expr_id=expr from_config(Config {
        nickname: None,
        ..Default::default()
    }) (hir_id=HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 15 }), using parent expr
    .await (hir_id=HirId { owner: DefId(0:7 ~ default_struct_update[79f9]::foo), local_id: 49 })
```

b94246693a Simplify pointer handling. 
The existing derive code allows for various possibilities that aren't
needed in practice, which complicates the code. There are only a few
auto-derived traits and new ones are unlikely, so this commit simplifies
things.

- `PtrTy` has been eliminated. The `Raw` variant was never used, and the
  lifetime for the `Borrowed` variant was always `None`. That left just
  the mutability field, which has been inlined as necessary.
- `MethodDef::explicit_self` was a confusing `Option<Option<PtrTy>>`.
  Indicating either `&self` or nothing. It's now a `bool`.
- `borrowed_self` is renamed as `self_ref`.
- `Ty::Ptr` is renamed to `Ty::Ref`.

7a4fdcbbc5 Remove unnecessary fields from EnumNonMatchingCollapsed. 
The `&[ast::Variant]` field isn't used.

The `Vec<Ident>` field is only used for its length, but that's always
the same as the length of the `&[Ident]` and so isn't necessary.

b33c6e1bd8 Do not error on the param_env during inlining. 
This created unexpected diagnostics while compiling alga:

Turns out that we don't need this diagnostic as we disable inlining when
it would trigger an ICE.

5999f34ff6 Don't assert polymorphization has taken effect in const eval 
Const eval no longer runs MIR optimizations so unless this is getting
run as part of a MIR optimization like const-prop, there can be unused
type parameters even if polymorphization is enabled.

Rollup merge of #98688 - RalfJung:from-mplace, r=oli-obk 
interpret: add From<&MplaceTy> for PlaceTy

We have a similar instance for `&MPlaceTy` to `OpTy`. Also add the same for `&mut`.

This avoids having to write `&(*place).into()`, which we have a few times here and at least twice in Miri (and it comes up again in my current patch).

7fda86249f promote placeholder bounds to 'static obligations 
In NLL, when we are promoting a bound out from a closure,
if we have a requirement that `T: 'a` where `'a` is in a
higher universe, we were previously ignoring that, which is
totally wrong. We should be promoting those constraints to `'static`,
since universes are not expressible across closure boundaries.
