jgruber edef59ca27 Reland "[build] Disable slow asserts for v8_enable_fast_mksnapshot" 
This is a reland of 7a0d6a5000

Original change's description:
> [build] Disable slow asserts for v8_enable_fast_mksnapshot
>
> Slow asserts double the time spent in mksnapshot. While we want them
> enabled on our bot builds, local builds should be fast and don't
> necessarily need them.
>
> This also adds v8_enable_fast_mksnapshot as default in gm.py.
