Proposal: support for v8-lite add a v8 jitless build to be used with deno

[frank-dspeed]

the new v8 lite project will be merged soon into the --jitless mode flag https://v8.dev/blog/v8-lite so it will not only allow to pre allocate memory it will also save up to 35% memory traded for some performance so it will run even better on devices with a small memory footprint

Enables

• Running on IoT Devices more memory efficient
• IOS & Android Support
• Better for big Data and Memory based Cloud Computing like ML Research.

This is more of a rusty_v8 thing than a Deno thing. https://github.com/denoland/rusty_v8. Even if it made it to Deno it would first need to be in rusty_v8.

Oh you're correct but in general, as deno ships with v8, it can be open here as a reference till something is done in that direction.

Deno ships with rusty_v8, which includes v8.

You can already run Deno in V8 jitless mode: deno run --v8-flags="--jitless". It is just painfully slow. V8 lite mode is also supported via --v8-flags="--lite-mode". I am not sure everything works, but it is enough for initial testing.

@lucacasonato amazing how fast we as a community did ship this features 👍
