Revert of Revert of Update V8 to version 4.3.10. (patchset #1 id:1 of https://codereview.chromium.org/961143003/)

Reason for revert:
This revert also didn't help. Relanding. Maybe something happened on these bots? The output of one test suggests to reinstall the build deps:
http://build.chromium.org/p/chromium.linux/builders/Linux%20Tests%20%28dbg%29%281%29%2832%29/builds/10450/steps/gfx_unittests/logs/PlatformFontLinuxTest.DefaultFont

It's of course odd that this problem exists on different bots...
