The new `FacetValue` instruction represents `C as I` for some type `C` and facet type `I`. It is named `FacetValue` instead of just `Facet` to parallel the `FacetType` instruction. This PR uses this instruction represent the facet value `Self` in an `impl` declaration. This instruction will be used in the future to also support things like: * `C as I` where `C` is a class; and * forming a specific for a generic with a `T:! I` parameter where `T` is being given a concrete value. (Here `I` is an interface or other non-`type` facet type.) Also do some renaming and add some comments to make things a bit more clear. * `FacetTypeAccess` -> `FacetAccessType` to clarify this is not access of a facet type, but access of the type of a facet * `.facet_id` -> `.facet_value_inst_id` to parallel the `FacetValue` instruction `FacetAccessWitness` will be in a future PR. --------- Co-authored-by: Josh L <josh11b@users.noreply.github.com> Co-authored-by: Richard Smith <richard@metafoo.co.uk>
