deps: cherry-pick 78c0be52d from V8 upstream
Original commit message:
ValueSerializer: Promote scheduled exceptions from wasm::ErrorThrower.
wasm::ErrorThrower doesn't actually throw exceptions, it just schedules them.
As a result, this exception isn't handled properly by code which expects
ValueDeserializer to actually throw. For instance, the unit tests use a
TryCatch to catch and handle expected exceptions in unit tests.
Before this patch, I see local unit test failures because a wasm decode test
schedules one, but it isn't caught (and instead causes Context::New to fail
at the beginning of the next test).

deps: cherry-pick bf511b426 from V8 upstream
Original commit message:
ValueSerializer: Support efficiently reading and writing one-byte strings.
memcpy is faster than UTF-8 encoding/decoding. This yields 10-20% wins on
serializing and deserializing long ASCII strings, according to
blink_perf.bindings -- and these are already in a fast path where the entire
string is known to be ASCII (but this has to be checked). The win may be
larger for strings in Latin-1 but not ASCII (though I suspect this is an
uncommon case).
A change is also made to make ValueSerializerTest.EncodeTwoByteStringUsesPadding
survive wire format version number changes.
This is the first of a series of wire format changes from the previous Blink
format. The deserializer continues to be able to read the old format, but
Chromium M56 will no longer be able to read the messages written by this, in M58.

deps: cherry-pick 6f1639ed1 from V8 upstream
Original commit message:
ValueSerializer: Distinguish between 'undefined' and an absent property.
Dealing with this case requires a wire format change. It is possible that an
element can be absent even in an array where the dense format was chosen
(because the array initially had no holes), if the elements are modified while
they are being serialized. In this case, a new tag for the "hole" is emitted.
The logic to treat undefined in dense arrays as an absent property is restricted
to versions of the wire format that this tag did not exist.

Original commit message:
ValueSerializer: Check for zero length before casting to FixedDoubleArray.
Even though the elements kind is FAST_DOUBLE_ELEMENTS, if length is zero
the isolate's empty_fixed_array is used. It's illegal to cast this to
FixedDoubleArray, so we avoid the cast.

deps: cherry-pick 591cc0b4c from V8 upstream
Original commit message:
ValueSerializer: Share string encoding code with String and RegExp objects.
This avoids the need to pull in the UTF-8 encoding code from the public API,
and allows it to take advantage of any supported way that i::String can be
encoded (one- or two-byte).
Backward compatibility is maintained, but this is the behavior beginning
with this version.

deps: cherry-pick 8990399dc from V8 upstream
Original commit message:
ValueDeserializer: Only allow valid keys when deserializing object properties.
The serializer won't ever write a more complex object. Not validating this
allows other things to be used as keys, and converted to string when the
property set actually occurs. It turns out this gives an opportunity to trigger
OOM by giving an object a key which is a very large sparse array (whose string
representation is very large).
This case is now rejected by the deserializer.

deps: cherry-pick 68960eeb7 from V8 upstream
Original commit message:
ValueDeserializer: Make sure that an exception is the legacy path.
The entry points to the deserializer are responsible for ensuring that an
exception is pending by the time they return. Some failures throw exceptions
themselves, while others (like errors in the format) are exceptions caused by
the deserializer, not coming from the runtime.
Like the non-legacy path, a default deserialization exception should be thrown
in such cases.

Cr-Commit-Position: refs/heads/master@{#43281}
deps: cherry-pick 654351997 from V8 upstream
Original commit message:
ValueSerializer: Add an explicit tag for host objects.
This makes it no longer necessary to ensure that V8 and Blink have non-colliding
tags, which makes it easier for them to evolve independently, and also makes
the wire format more suitable for other V8 embedders, who would not
necessarily be surveyed before V8 introduced a new tag that might collide
with theirs.

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.
