Bug 798624 - Specialize low-level character access to JSStableString; r=luke, rs=Waldo

Browse Source 
Implements JSStableString::chars() and pushes StableCharPtr into the interface
at several key choke-points. This will solidly enforce the requirement that we
have uninlined jschar*s in places that we may GC with a jschar* on the stack.
