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.

e89ad9f345 Allow ambiguous autoderef with defininte guidance.

d674d7185d Represent opaque types with TyKind::OpaqueType 
... instead of using `AliasTy`. Chalk turns the alias type into the
placeholder during unification anyway, which confuses our method
resolution logic.

Fixes #9530.
