This is a reland of 63ecddc814
Original change's description:
> [runtime] Remove the construct_stub field of the SFI
>
> Don't dispatch based on the construct_stub field anymore. Rather than
> read it out and jump to the construct stub, we can switch on the
> builtin_id.
>
> Builtins will always have builtin_id as a Smi, so this signals we need
> to jump to JSBuiltinsConstructStub. The only exception is for uncompiled
> functions, which will have kCompileLazy as the builtin_id, but need to
> jump to the generic stub instead.
>
> API function calls will have a FunctionTemplateInfo in the SFI
> function_data field, and need to go to the builtins stub as well.
>
> The final case is everything else, which should go to the generic stub.
>
> Bug: v8:7503
