Back memory lane... Fastload is 16 years old according to bugzilla (bug 68045), but was removed 6 years ago (bug 654489) in favor of startupcache (bug 592943), which, BTW, we're not generating at build time anymore as of Firefox 55 (bug 1351071) (but we're still generating it at startup time). I don't remember what fastload was keeping around, but startupcache stores pre-parsed JS, but I'm not sure of the details, whether that's some AST or something else. Storing bytecode instead could still be a win.
