Merge #9954 
9954: feat: Show try operator propogated types on ranged hover  r=matklad a=Veykril

Basically this just shows the type of the inner expression of the `?` expression as well as the type of the expression that the `?` returns from:
![Code_wIrCxMqLH9](https://user-images.githubusercontent.com/3757771/130111025-f7ee0742-214a-493b-947a-b4a671e4be92.png)

Unless both of these types are `core::result::Result` in which case we show the error types only.
![Code_Xruw5FCBNI](https://user-images.githubusercontent.com/3757771/130111024-f9caef82-92e4-4070-b3dd-f2ff9e5d87a9.png)

If both types are `core::option::Option` with different type params we do not show this special hover either as it would be pointless(instead fallback to default type hover)

Very much open to changes to the hover text here(I suppose we also want to show the actual type of the `?` expression, that is its output type?).

Fixes #9931

Merge #9807 
9807: Implicit `Sized` bounds r=iDawer a=iDawer

This should close #8984 

`hir_ty`:
- Type parameters, associated types and `impl Trait` are `Sized` by deafault except `Self` in a trait.
- Implicit `Sized` bound is added to end of predicate list. It does not check if such bound is present already. Also it does not track the bound is implicit.
- Allowed ambiguous unsize coercion if Chalk returns definite guidance.
- Allowed ambiguous autoderef if Chalk returns definite guidance.

`hir_def`:
- `ItemTree` pretty printing shows `?Sized` bounds.

`HirDisplay`:
- `impl Trait` with weird bounds rendered correctly.
- `Sized`/`?Sized` bounds are not shown if they are default.

Merge #9453 
9453: Add first-class limits. r=matklad,lnicola a=rbartlensky

Partially fixes #9286.

This introduces a new `Limits` structure which is passed as an input
to `SourceDatabase`. This makes limits accessible almost everywhere in
the code, since most places have a database in scope.

One downside of this approach is that whenever you query limits, you
essentially do an `Arc::clone` which is less than ideal.

Let me know if I missed anything, or would like me to take a different approach!

8717: Update match checking algorithm r=iDawer a=iDawer

I've recently got interest in the match checking to extend the current algo to support reporting witnesses of non-exhaustiveness.
It appears the algo is outdated from rustc's implementation. I decided to rewrite it based on the latest rustc's version. It is a diff-based port to ra codebase. That means you can diff-compare these files to rustc.
I'm striving to keep minimal ra-related changes in the algo to make it easier to backport future changes from the upstream.

Based on upstream algorithm of version rust-lang/rust 1.52.0-nightly (25c15cdbe 2021-04-22)
https://github.com/rust-lang/rust/blob/25c15cdbe/compiler/rustc_mir_build/src/thir/pattern/usefulness.rs

The goal of this PR is to cover the current `missing-match-arm` diagnostic.

What is remaining to do:
- [x] Error handling. The errors that are unrelated to match checking will be handled before the check. Just like how it made in rustc.
  - [x] Lowering `hir_def::expr::Pat` to `hir_ty::diagnostics::match_check::Pat`. rustc's match checking works on top of `rustc_mir_build::thir::Pat`, which is lowered from `hir::Pat` and carries some extra semantics used by the check. All unrelated checks are done there. RA could use this to rule out running the check on unimplemented cases (`Pat::ConstBlock`, etc).
  - [x] ~~Proper~~Loose typecheck of match arm patterns (https://github.com/rust-analyzer/rust-analyzer/pull/8840, https://github.com/rust-analyzer/rust-analyzer/pull/8875).
- [x] Tests from `hir_ty::diagnostics::match_check::tests`.
- [x] Clean up `todo`s
- [x] Test run on real repos https://github.com/rust-analyzer/rust-analyzer/pull/8717#issuecomment-847120265.

5c9f31d4c2 internal: move diagnostics to hir 
The idea here is to eventually get rid of `dyn Diagnostic` and
`DiagnosticSink` infrastructure altogether, and just have a `enum
hir::Diagnostic` instead.

The problem with `dyn Diagnostic` is that it is defined in the lowest
level of the stack (hir_expand), but is used by the highest level (ide).

As a first step, we free hir_expand and hir_def from `dyn Diagnostic`
and kick the can up to `hir_ty`, as an intermediate state. The plan is
then to move DiagnosticSink similarly to the hir crate, and, as final
third step, remove its usage from the ide.

One currently unsolved problem is testing. You can notice that the test
which checks precise diagnostic ranges, unresolved_import_in_use_tree,
was moved to the ide layer. Logically, only IDE should have the infra to
render a specific range.

At the same time, the range is determined with the data produced in
hir_def and hir crates, so this layering is rather unfortunate. Working
on hir_def shouldn't require compiling `ide` for testing.
