## Message

```
Sema: improve non-exhaustive enum support

 * remove false positive "all prongs handled" compile error for
   non-exhaustive enums.
 * implement `@TypeInfo` for enums, except enums which have any
   declarations is still TODO.
 * `getBuiltin` uses nomespaceLookup/analyzeDeclVal rather than
   namespaceLookupRef/analyzeLoad. Avoids a detour through an
   unnecessary type, and adds a detour through a caching mechanism.
 * `Value.eql`: add missing code to handle enum comparisons for
   non-exhaustive enums. It works by converting the enum tags to numeric
   values and comparing those.

```
