This allows us to import the table for a given impl only once, while we can import many ImplWitness instructions with different specifics for a generic impl. For example in convert_facet_value_to_narrowed_facet_type.carbon we see that a single witness table is imported for the BitAnd interface, with multiple witnesses (for different specifics) imported and sharing the same table. The ImplWitnessTable now contains a back-link to the Impl the witness is for, allowing inst namer to name that interface in the textual semir, and allowing the interface to be found when debugging from a witness. --------- Co-authored-by: Richard Smith <richard@metafoo.co.uk>
