Removed deprecated functions from v8's external API.
...
Removed the following deprecated functions:
* Object::GetPointerFromInternalField
* Object::SetPointerInInternalField
* External::Wrap
* External::Unwrap
* Context::GetData
* Context::SetData
They have been deprecated in the 3.15 branch and are not used by Chrome anymore.
Furthermore, judging from bug reports and email threads, embedders like node.js
and others are already using 3.15, too. All removed API entries can be emulated
by a one-liner, so adapting should not be hard for anybody.
We want to introduce more deprecations soon, but to keep things simple and avoid
having old and not-so-old deprecations in v8.h, the 3.15 deprecations are now
removed.
In general, the strategy of keeping deprecated things for one stable release and
then removing them seems to be a good compromise between a maintenance nightmare
and annoying external embedders. :-)

Fix shared function info code replacement.
...
This fixes a corner case when the unoptimized code for a shared function
info is replaced while the function is enqueued as a flushing candidate.
Since the link field is stored within the code object, the candidates
list got destroyed.

Added %FlattenString and use it to speed up a regression test.
...
Flattening strings is relatively costly and by doing it after every duplication
we avoid combinatorial explosion.
Note that flattening could have been done by e.g. using a regular expression,
too, but this is just another implementation detail and %FlattenString seems
general enough to be useful in other tests, too.

we store an AllocationSiteInfo object right after the JSArray, with a pointer to the

of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to

There are now NONE and NONE64 RelocInfo types, but only ARM uses them
both at the same time. They were added in:
https://chromiumcodereview.appspot.com/11191029/
I'll rename NONE to NONE32 in a later CL.
This CL cleans up the RelocInfo::NONE usage by:
- Using RelocInfo::IsNone when testing for NONE-ness.
- Using NONE on 32-bit platforms (MIPS and IA32), and NONE64 on 64-bit
platforms (x64).
This cleans up the code and prevents it from evolving bugs in the future
because NONE32 and NONE64 are used in misleading ways.

Add methods to allow resuming execution after calling TerminateExecution().
...
Two new methods are added to allow embedders to determine that execution
should be resumed at a particular point in the stack without being forced
to unwind all JS frames.
* V8::ResumeExecution() -- When execution is terminated via a call to
V8::TerminateExecution(), this method can be called to clear the
termination exception so that the engine can continue to be used.
* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
exception, HasTerminated() will return true to indicate it is valid to
call V8::ResumeExecution() if desired.
A test case is added to cctest/test-thread-termination.cc.

Object.observe: prevent observed objects from using fast elements.
...
This is necessary because polymorphic stores generally
do not perform a map check but only an instance type check,
which misses out on changes in the observation status.
Unfortunately, there currently is no efficient way in V8
to maintain that optimisation in the presence of Object.observe.
