Richard Smith 145f878ce8 Allow extend adapt of non-class types. (#4544) 
Stop rejecting `extend adapt` of non-class types such as struct and
tuple. These don't actually work just yet because name lookup into
struct and tuple types is a special case that doesn't handle adapters,
but this gets us a bit closer.

This also slightly improves error recovery for name lookup into an
invalid scope.
