      Remove per-parameter position var scope · 1b450a17
      Shu-yu Guo authored
      The spec was normatively changed to simplify var scopes for parameter
      expressions. Previously there was a per-parameter var scope in sloppy
      mode so direct evals could introduce vars that did not escape the
      parameter position. That semantics is complex both for the programmer
      and implementation and has resulted in bugs in the past. Furthermore, it
      has never been fully interoperable (with Safari in particular). The spec
      was instead changed to be simpler: to have a single var scope for
      sloppy evals in parameters that encloses the parameter scope and body
      scope.
      
      This simplification lets us remove expression-scope-reparenter.
      
      Drive-by removal of stale reference to PatternRewriter.
