• VM/Machine.cpp:
• VM/Machine.h: (JSC::makeHostCallFramePointer): (JSC::isHostCallFrame): (JSC::stripHostCallFrameBit): Moved some things to the header so JSGlobalObject could use them.

• kjs/JSGlobalObject.h: (JSC::JSGlobalObject::JSGlobalObjectData::JSGlobalObjectData): Call the new makeHostCallFramePointer API, since 0 no longer indicates a host call frame.
