Make the `Query` enum a simple struct.
A lot of code in `rustc_query_system` is generic over it, only to encode an exceptional error case: query cycles.
The delayed computations are now done at cycle detection.
Refactor inlining decisions so that inexpensive criteria are considered first:
1. Based on code generation attributes.
2. Based on MIR availability (examines call graph).
3. Based on MIR body.
`escape_unicode`, `escape_default`, `len_utf8`, `len_utf16`, to_ascii_lowercase`, `eq_ignore_ascii_case`
`u8` methods `to_ascii_lowercase`, `to_ascii_uppercase` also must be made const
u8 methods made const

Jsondocck improvements
Adds 2 new commands, ```@is``` and ```@set`.``
```@is``` works like ```@has`,`` except instead of checking if any value matches, it checks that there is exactly one value, and it matches. This allows more precise testing.
```@set``` gets a value, and saves it to be used later. This makes it possible to check that an item appears in the correct module.
Once this lands, the rest of the test suite can be upgraded to use these.

Remove many RefCells from DocContext
I left some of them so this change doesn't balloon in size and because
removing the RefCell in `DocContext.resolver` would require compiler
changes.
Thanks to `@jyn514` for making this a lot easier with #82020!

Consider auto derefs before warning about write only fields
Changes from #81473 extended the dead code lint with an ability to detect
fields that are written to but never read from. The implementation skips
over fields on the left hand side of an assignment, without marking them
as live.
A field access might involve an automatic dereference and de-facto read
the field. Conservatively mark expressions with deref adjustments as
live to avoid generating false positive warnings.
Closes#81626.
Implement -Z hir-stats for nested foreign items
An attempt to compute HIR stats for crates with nested foreign items results in an ICE.
```rust
fn main() {
extern "C" { fn f(); }
}
```
```
thread 'rustc' panicked at 'visit_nested_xxx must be manually implemented in this visitor'
```
Provide required implementation of visitor method.
