Specifically: - In parser, check that all exports are defined. - Move JSModule allocation from parser to scope resolution. - Move JSModule linking from full codegen to scope resolution. - Implement module accessors for exported value members. - Allocate module contexts statically along with JSModules (to allow static linking), but chain them when module literal is evaluated. - Make module contexts' extension slot refer to resp. JSModule (makes modules' ScopeInfo accessible from context). - Some other tweaks to context handling in general. - Make any code containing module literals (and thus embedding static references to JSModules) non-cacheable. This enables accessing module instance objects as expected. Import declarations are a separate feature and do not work yet.
