The bytecode generator did not necessarily know for which scope, and thus language mode, it was generating code, because it only tracked scopes that have a context. This led to wrong behavior in some examples involving class expressions (which are always in strict mode). With this CL, the bytecode generator explicitly tracks the current scope, independent of whether it has a context.
