Version 3.26.30 (based on bleeding_edge revision r21129)
Introduce a microtask suppression scope and move microtask methods to isolate (Chromium issue 369503).
Re-enable Object.observe and add enforcement for security invariants.
Move cache line size calculation directly into CPU::FlushICache (Chromium issue 359977).
Generation of our home-grown memmove doesn't depend on serializer state anymore (Chromium issue 359977).
Fix |RunMicrotasks()| leaking reference to the last context being run on.
Object.defineProperty shouldn't be a hint that we're constructing a dictionary (Chromium issue 362870).
Performance and stability improvements on all platforms.
