Revert of Update V8 to version 4.3.10. (patchset #1 id:1 of https://codereview.chromium.org/965873003/)

Reason for revert:
Speculative revert to see whether this affects some failing tests on linux:

http://build.chromium.org/p/chromium.linux/builders/Linux%20Tests%20%28dbg%29%281%29%2832%29

The two other Chromium commits in the narrowed-down range were reverted but that didn't help.
