Title: Fix "cannot encode region variables" error

The basic problem was that vtables were not being resolved. The fix uncovered another issue, which was that the syntax extensions were not creating method calls properly and were relying on outdated code in typeck, so I fixed that too.

Resolves issues #3888, #4036, #4492.
