Prepare gcmole.cc for the next update: - Print possible GC locations when discovering stale/dead variables - Make error messages less confusing for the modern V8 engineer - Prepare gcmole to read suspects.allowlist instead of .whitelist - Use more readable variable names - Only log non-found types with --verbose - Change the currently unusued gccauses format in gcmole.py and support loading it back in gcmole.cc - Implemented first basic gc call-chain printing (disabled by default) GCmole packaging: - Add debug mode to bootstrap.sh build script - Update gcmole.py run instructions in bootstrap.sh and package.sh Bug: v8:10009 Change-Id: I369d48baa2980455d2e8f57e7a803d0384fe83f1 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3480095 Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Maya Lekova <mslekova@chromium.org> Commit-Queue: Camillo Bruni <cbruni@chromium.org> Cr-Commit-Position: refs/heads/main@{#79357}
