Introduce a new public API called CodeEventListener to allow embedders
to better support external profilers and other diagnostic tools without
relying on unsupported methods like --perf-basic-prof.

The fixup isn't upstream?

The patch didn't build because the Address typedef is different between V8 6.7 and V8 6.8 (see https://chromium-review.googlesource.com/c/v8/v8/+/988657). I can try to float https://chromium-review.googlesource.com/c/v8/v8/+/988657 as well instead of changing the Patch to work on V8 6.7.

It's a big patch. I prefer we stick with your fix.

For context: this API will allow users to generate the map file required by Linux perf during runtime. Today the file is generated by --perf-basic-prof, which will keep writing to the file during the entire application lifetime, leading to file growth problems. Sice V8 6.7 fixed Linux perf for Interpreted Functions, it would be really nice to also have this API when V8 6.7 lands on Node.js v10.x.

Cherry-picking one more commit here (v8/v8@b20faff) to fix a bug when using this API with --interpreted-frames-native-stack on. If there are no objections I'd like to land this tomorrow.

    [log] fix ExistingCodeLogger behavior on edge case

    ExistingCodeLogger was behaving incorrectly when the
    CodeEventHandler API was used in combination with
    --interpreted-frames-native-stack.  Instead of collecting copied
    trampolines as InterpretedFunction:functionName, they were being
    collected as Builtin:IntepreterEntryTrampolines.  This patch adds
