Original commit message:
Reland "[api] allow v8::Data as internal field"
This is a reland of commit 0aa622e12893e9921c01a34ce9507b544e599c4a
The original patch tried to run a test that calls exit() in the
fatal error handler in parallel, which would not work. This marked
the test with TEST() to avoid running it in parallel.

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.

This commit applies some secondary changes in order to make `make test`
pass cleanly:
* disable broken postmortem debugging in common.gypi
* drop obsolete strict mode test in parallel/test-repl
* drop obsolete test parallel/test-v8-features

This commit removes the simple/test-event-emitter-memory-leak test for
being unreliable with the new garbage collector: the memory pressure
exerted by the test case is too low for the garbage collector to kick
in. It can be made to work again by limiting the heap size with the
--max_old_space_size=x flag but that won't be very reliable across
platforms and architectures.
