Check that a @retains annotation only mentions references that can be tracked. This check is performed at Typer.

Attributes
If tp is a capturing type, check that all references it mentions have non-empty capture sets. Also: warn about redundant capture annotations. This check is performed after capture sets are computed in phase cc.

Attributes
Warn if ann, which is the tree of a @retains annotation, defines some elements that are already accounted for by other elements of the same annotation. Note: We need to perform the check on the original annotation rather than its capture set since the conversion to a capture set already eliminates redundant elements.
