Adds support for: - Type literals - By-value reference to top-level or static function - Const constructor invocation inside const literal list or map Nested const expressions are linearized to LetPrims, and we rely on the dart_tree to inline all primitives (since non-const variable references may not occur in a const expression). There are still a bunch of constants that we support but don't actually treat as constants. Reference to top-level constants are still treated as a getter invocations, for instance. We bail out on local constant declarations since they must either be inlined at multiple places or we must generate a constant declaration for them.
