> This CL removes the extension slot from contexts that don't need

Reland x3 "[runtime] Remove extension slots from context objects"
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.
>

Reland x3 "[runtime] Remove extension slots from context objects"
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.
>
> Bug: v8:9744
