3263: Implement unsizing coercions using Chalk r=matklad a=flodiebold These are coercions like `&[T; n] -> &[T]`, which are handled by the `Unsize` and `CoerceUnsized` traits. The impls for `Unsize` are all built in to the compiler and require special handling, so we need to provide them to Chalk. This adds the following `Unsize` impls: - `Unsize<[T]> for [T; _]` - `Unsize<dyn Trait> for T where T: Trait` - `Unsize<dyn SuperTrait> for dyn SubTrait` Hence we are still missing the 'unsizing the last field of a generic struct' case.
