Cleanup Named Targets (#1311)

* Add CleanupNamedTargets Transform

Adds a new transform, CleanupNamedTargets, that will convert
ReferenceTargets to InstanceTargets if any ReferenceTargets are found
to be actually pointing at instances.

This fixes an issue where a ComponentName pointing at an instance will
be converted to a ReferenceTarget. Later on, this ReferenceTarget will
not be properly renamed by other transforms, e.g.,
EliminateTargetPaths.
