Choice nodes may know that they are never not at the start of input.
This can remove start_of_input assertions in cases where they are statically known to fail.
The initial loop is unrolled once if the regexp might check for the start of input. Only the first iteration may be at the start, the following loop knows that it isn't.

Thus, instead of the following profiler records:
   1.5%    1.5%   LazyCompile: <anonymous>
we'll now have these:
   1.5%    1.5%   LazyCompile: <anonymous> richards.js:309

Basically, I translated two functions from messages.js into C++.
In the next CL I will update messages.js to use added native functions.

Changed the debugger API to allow only one debug event listener to be registered. The public API now only has SetDebugEventListener instead of AddDebugEventListener and RemoveDebugEventListener.

Moved the registrered debug event listener from the context to a global handle in the Debugger class. Storing it in the context did not make much sense.

Changed a lot of tests to handle the API change.

The ExternalReferenceTable population code was code driven, using the list macro callbacks to call an Add() function.  Additionally this Add() function was defined in the class defintion, making it inline.  This caused this single function to be ~100k of code.  It is now mostly table driven, but there are still some cases left as code, and these could be improved in the future for further reduction in binary size.
