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 .

Fix wrong handling of bare dyn Trait
exposed by canonicalizer fix
...
The self type in the `dyn Trait` trait ref should always be ^0, but we didn't
put that in there in the bare case.

Fix #2705
...
The `-` turned into a `+` during a refactoring.
The original issue was caused by `Read` resolving wrongly to a trait without
type parameters instead of a struct with one parameter; this only fixes the
crash, not the wrong resolution.
