Proposal #5168 defines when a facet type must be identified or complete, and what it means for an interface and a named constraint to be identified or complete. This updates the toolchain to match the requirements. This implements identification of a facet type to require completed named constraints and to include any interfaces from named constraints into the resulting IdentifiedFacetType. To complete a facet type, each interface in the IdentifiedFacetType, and any interface named though a require declaration from them, must be complete.
