Version 3.19.4
Fixed edge case in stack trace formatting. (Chromium issue 237617)
Fixed embedded new-space pointer in LCmpObjectEqAndBranch. (Chromium issue 240032)
Made Object.freeze fast (issue 1858, Chromium issue 115960)
Fixed bogus deopt in BuildEmitDeepCopy for holey arrays. (Chromium issue 242924)
Performance and stability improvements on all platforms.
