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.
