Conservatively assume dropping a generator touches its upvars, via locals' dtors.

This is meant to address rust-lang/rust#49918.

Review feedback: put back comment justifying skipping interior traversal.

Review feedback: dropck generators like trait objects: all their upvars must
outlive the generator itself, so just create a DtorckConstraint saying so.
