  Fix 21590 - assignment inside assert accepted for -checkaction=context

  The rewrite introduced a temporary which hid the assignment inside of
  `assert(...)` and hence prevented the error.

  The fix is to omit the additional temporary for `AssignExp` and use
  the assigned variable directly. The temporary is unecessary anyways
  and the following semantic analysis will raise an appropriate error.
