9fc844b760 V8_Fatal now prints C++ stack trace in debug mode.
Currently only supported on Linux. When compiled with GCC, also demangles C++ identifier names.

Should make debugging those flaky crashes on buildbots easier... :)

4cd41edcd9 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.

23d681c50b Removed RuntimeProfilerRateLimiter class and RuntimeProfiler::IsSomeIsolateInJS.
Removing the former was basically a consequence of removing the latter. The net
effect is, apart from less code, that the signal sender thread is much more
explicit about its logic now.

76375de29d 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.
