Reland "[torque] Port builtins-number-gen to Torque"

This is a reland of 4482f988
It's identical to the original CL so ..

TBR=jgruber@chromium.org,tebbi@chromium.org

Original change's description:
> [torque] Port builtins-number-gen to Torque
>
> - Ports everything except Add.
>
> Builtins generated from this CL are slightly larger, e.g. Subtract
> is 424 bytes on x64, as opposed to 400 bytes for the CSA version.
> See https://crbug.com/v8/10521
