Description of change
This removes the diagnostic code for the issue described in https://bugs.chromium.org/p/chromium/issues/detail?id=454297. That issue is private, probably due to the fact that it contains information about a security vulnerability.
The original issue was fixed in V8 by https://codereview.chromium.org/1286343004, which was integrated into node v4.x with c4317257, so there's no need for the corresponding diagnostic code anymore.
Original commit message:
[heap] Remove debugging code of crbug/454297.
