Simplify implementation of assignment-to-const checks.

Also, add test that assignment to function name is a syntax error with harmony scoping.

Does not fix issue 2243 directly, but with ES6, the required behaviour will change to what is implemented already anyway.

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.

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
