Introduces a new BindingVal which combines direct and
default binding for regions. This allows us to simply a lot of code. A
further simplification could be done is that many methods of
regionstore can only work on Store instead of GRState.

Implement the core checking for compatible exception specifications in assignment and initialization.
The exception specification of the assignee must be the same or a subset of the target. In addition, exception specifications on arguments and return types must be equivalent, but this is not implemented yet.
This currently produces two diagnostics for every invalid assignment/initialization, due to the diagnostic produced outside PerformImplicitConversion, e.g. in CheckSingleInitializer. I don't know how to suppress this; in any case I think it is the wrong place for a diagnostic, since there are other diagnostics produced inside the function. So I'm leaving it as it is for the moment.

Minor tweaks for code-completion:
- Filter out unnamed declarations
- Filter out declarations whose names are reserved for the

- Place OVERLOAD: or COMPLETION: at the beginning of each
