Robert Griesemer 91a40f43b6 go/types, types2: don't report assignment mismatch errors if there are other errors ...

Change the Checker.use/useLHS functions to report if all "used"
expressions evaluated without error. Use that information to
control whether to report an assignment mismatch error or not.
This will reduce the number of errors reported per assignment,
where the assignment mismatch is only one of the errors.
