        A little more encapsulation for the heap: Removed CollectorHeapIterator
        https://bugs.webkit.org/show_bug.cgi?id=54298
        
        CollectorHeapIterator is a God object that knows the internals of each
        of the pieces of the heap. This undermines the encapsulation I'm trying
        to achieve by splitting concepts into different classes.
        
        As an alternative, I've given each class a forEach iteration function,
        which takes a functor as an argument. Now, each class just needs to
        know how to iterate the things it knows about.

        * GNUmakefile.am:
        * JavaScriptCore.exp:
        * JavaScriptCore.gypi:
        * JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCore.vcproj: Removed CollectorHeapIterator.

        * debugger/Debugger.cpp:
        (JSC::Recompiler::Recompiler):
        (JSC::Recompiler::~Recompiler):
        (JSC::Recompiler::operator()):
        (JSC::Debugger::recompileAllJSFunctions): Updated to use forEach interface
        instead of an iterator.

        * runtime/CollectorHeapIterator.h: Removed.

        * runtime/Heap.cpp:
        (JSC::TypeCounter::TypeCounter):
        (JSC::TypeCounter::typeName):
        (JSC::TypeCounter::operator()):
        (JSC::TypeCounter::take):
        (JSC::Heap::protectedObjectTypeCounts):
        (JSC::Heap::objectTypeCounts): Added forEach and removed iterator.

        * runtime/Heap.h:
        (JSC::Heap::forEach):
        * runtime/JSGlobalData.cpp:
        (JSC::Recompiler::operator()):
        (JSC::JSGlobalData::recompileAllJSFunctions):

        * runtime/MarkedBlock.h:
        (JSC::MarkedBlock::forEach): Added forEach. Removed friend declaration
        for CollectorHeapIterator. Now, we can make all our data private and
        change it without breaking any other classes.

        * runtime/MarkedSpace.cpp:
        * runtime/MarkedSpace.h:
        (JSC::MarkedSpace::forEach): Added forEach and removed iterator.
