2bf81922f7 internal: more reasonable grammar for blocks
Consider these expples

        { 92 }
  async { 92 }
    'a: { 92 }
   #[a] { 92 }

Previously the tree for them were

  BLOCK_EXPR
    { ... }

  EFFECT_EXPR
    async
    BLOCK_EXPR
      { ... }

  EFFECT_EXPR
    'a:
    BLOCK_EXPR
      { ... }

  BLOCK_EXPR
    #[a]
    { ... }

As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers

  BLOCK_EXPR
    STMT_LIST
      { ... }

  BLOCK_EXPR
    async
    STMT_LIST
      { ... }

  BLOCK_EXPR
    'a:
    STMT_LIST
      { ... }

  BLOCK_EXPR
    #[a]
    STMT_LIST
      { ... }

a2d9f7d7bb Avoid type inference panic on bitslice methods
Should fix #10090, #10046, #10179.
This is only a workaround, but the proper fix requires some bigger
refactoring (also related to fixing #10058), and this at least prevents
the crash.

Merge #10202
10202: fix: Type param hover shows correct sized bounds. r=flodiebold a=iDawer

Closes  #9949

This adds implicit `: Sized` bound to type parameters at lowering step.

Hovering on type parameter does not show it's `: Sized` bound be it set explicitly or implicitly. This is because it doesn't track that the bound was set implicitly.

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

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.
