Store named constant values in the AST ( #1011 )
...
This enables us to stop using `Env` in the typechecker. As a byproduct, this commit also restructures the interpreter to handle run-time global initialization as part of ordinary execution, using the Action stack.

Add name accessor to NamedEntityView ( #994 )
...
This required changing BindingPattern::name() to return `"_"` instead of nullopt when representing a `"_"` binding.
Semi-related drive-by fixes:
- Update BindingPlaceholderValue to expose a NamedEntity instead of a string name, and stop exposing its type.
- Drop the unused SourceLocation parameter of ValueEqual

Use resolved names in typechecker ( #974 )
...
As a byproduct, replace NamedEntity with a type-erasing wrapper NamedEntityView, eliminate virtual inheritance from the AST, and eliminate interfaces from gen_rtti.

Handle use-before-declare in static name lookup ( #967 )

Also remove inheritance from NamedEntity for some classes that don't need it.

Implement static name resolution ( #958 )
...
This doesn't actually use the results of name resolution, but it does verify that they are present.
Also ensures that name resolution and type checking are applied to deduced function parameters and the implicit call to `Main()`.

Start populating named entities in relevant locations. ( #919 )
...
This starts detecting naming collisions as a consequence of being able to determine when the name is declared twice in a given scope.
