deps: update v8 to 4.4.63.9

Upgrade the bundled V8 and update code in src/ and lib/ to the new API.

Notable backwards incompatible changes are the removal of the smalloc
module and dropped support for CESU-8 decoding.  CESU-8 support can be
brought back if necessary by doing UTF-8 decoding ourselves.

This commit includes https://codereview.chromium.org/1192973004 to fix
a build error on python 2.6 systems.  The original commit log follows:

    Use optparse in js2c.py for python compatibility

    Without this change, V8 won't build on RHEL/CentOS 6 because the
    distro python is too old to know about the argparse module.
