Reason for revert: This breaks gc-stress bot: https://chromegw.corp.google.com/i/client.v8/builders/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot # # Fatal error in ../../src/heap/mark-compact.cc, line 3715 # Check failed: Page::FromAddress(reinterpret_cast<HeapObject*>(*slot)->address()) ->IsFlagSet(Page::PAGE_NEW_NEW_PROMOTION). # I can reproduce locally, and local revert also fixes it -> revert.
