a4a4a1854e Fix type parameter defaults
They should not be applied in expression or pattern contexts, unless there are
other explicitly given type args.

3f42b2e837 Handle Self in values and patterns
I.e.
 - `Self(x)` or `Self` in tuple/unit struct impls
 - `Self::Variant(x)` or `Self::Variant` in enum impls
 - the same in patterns

Fixes #4454.

9faea2364d Use dyn Trait for working with databse
It improves compile time in `--release` mode quite a bit, it doesn't
really slow things down and, conceptually, it seems closer to what we
want the physical architecture to look like (we don't want to
monomorphise EVERYTHING in a single leaf crate).

d17c5416af Resolve Self::AssocTy in impls
To do this we need to carry around the original resolution a bit, because `Self`
gets resolved to the actual type immediately, but you're not allowed to write
the equivalent type in a projection. (I tried just comparing the projection base
type with the impl self type, but that seemed too dirty.) This is basically how
rustc does it as well.

Fixes #3249.

e4add45951 Fix #2467
The stand-alone `unify` requires that the type doesn't contain any type
variables. So we can't share the code here for now (without more refactoring)...

cf6809645e Handle cycles in impl types better
- impl Trait<Self> for S is allowed
 - impl Trait for S<Self> is an invalid cycle, but we can add cycle recovery for
   it in Salsa now
