Original commit message:
[cpu-profiler] Use instruction start as the key for the CodeMap
Previously we used the start address of the AbstractCode object. This
doesn't make sense for off-heap builtins, where the code isn't contained
in the object itself. It also hides other potential problems - sometimes
the sample.pc is inside the AbstractCode object header - this is
never valid.
There were a few changes necessary to make this happen:
- Change the interface of CodeMoveEvent. Now 'to' and 'from' are both
AbstractCode objects, which is nice because many users were taking
'to' and adding the header offset to it to try and find the
instruction start address. This isn't valid for off-heap builtins.
- Fix a bug in CodeMap::MoveCode where we didn't update the CodeEntry
object to reflect the new instruction_start.
- Rename the 'start' field in all of the CodeEventRecord sub-classes
to make it clear that this is the address of the first instruction.
- Fix the confusion in RecordTickSample between 'tos' and 'pc' which
caused pc_offset to be calculated incorrectly.
Bug: v8:7983

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.
