Use a filter instead of a visitor to deoptimize selected functions in a context.
...
This makes the DeoptimizeAll function O(n) instead of O(n^2) where n in the number of optimized functions.
Before this change, DeoptimizeAll iterated over the optimized function list and called DeoptimizingVisitor for each function. The visitor iterated over the optimized function list again to remove the functions that share the same optimized code.
This change partitions the optimized function list into one or more lists of related functions in one pass over the optimized function list.

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.
