        <rdar://problem/5950538> JSProfiler: Keep track of non-JS execution time
        We now have an extra node that represents the excess non-JS time.
        - Also changed "SCRIPT" and "anonymous function" to be more consistent
        with the debugger.

        * profiler/ProfileNode.cpp:
        (KJS::ProfileNode::stopProfiling): If this ProfileNode is the head node
        create a new child that has the excess execution time.
        (KJS::ProfileNode::calculatePercentages): Moved calculation of the
        percentages into a function since it's called from multiple places.
        * profiler/ProfileNode.h: Add the newly needed functions used above.
        (KJS::ProfileNode::setTotalTime):
        (KJS::ProfileNode::setSelfTime):
        (KJS::ProfileNode::setNumberOfCalls):
        * profiler/Profiler.cpp: renamed "SCRIPT" and "anonymous function" to be
        consistent with the debugger and use constants that can be localized
        more easily.
        (KJS::getCallIdentifiers):
        (KJS::getCallIdentifierFromFunctionImp):
