It isn't clear from that description, but the focus here is on the chrome JS that is part of the browser, rather than on websites. Reducing content process chrome JS memory usage is going to have to be a big focus for this effort, because I believe other browsers don't write their UI in JS, and the way JIT stuff works it is harder to share code memory between processes than with AOT compiled code. If you look at about:memory, there's already a decent breakdown of how much memory is used in JS for different things, but that doesn't help you figure out which individual scripts are taking up memory. JSMs and content scripts are run in only a few globals (to save memory), but that means that looking up how much memory a global uses doesn't tell you much.
