    > 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.
