Fix ExceptionState with empty context.

Fix ExceptionState with empty context.

Since NonThrowableExceptionState, TrackExceptionState, NoExceptionStateAssertionChecker and IgnorableExceptionState create no wrapper, we don't need to fix those exception state with empty context.

We need to fix ExceptionState. To ensure that all ExceptionStates are fixed, added ASSERT to ExceptionState::throwSecurityError and ExceptionState::throwDOMException.

Would you review this CL?

LGTM, assuming that you've confirmed that all call sites of ExceptionState pass
in a creation context to ExceptionState().
