    Original change's description:
    > [runtime] Remove extension slots from context objects
    >
    > 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.
