Context objects have an extension slot, which contains further additional data that depends on the type of the context. This CL removes the extension slot from contexts that don't need them, hence reducing memory. The following contexts will still have an extension slot: native, module, await, block and with contexts. See objects/contexts.h for what the slot is used for. The following contexts will not have an extension slot anymore (they were not used before): script, catch and builtin contexts. Eval and function contexts only have the extension slot if they contain a sloppy eval.
