Reviewed by Maciej Stachowiak. Fix for https://bugs.webkit.org/show_bug.cgi?id=21683 Don't create intermediate StructureIDs for builtin objects First step in reduce number of StructureIDs created when initializing the JSGlobalObject. - In order to avoid creating the intermediate StructureIDs use the new putDirectWithoutTransition and putDirectFunctionWithoutTransition to add properties to JSObjects without transitioning the StructureID. This patch just implements this strategy for ObjectPrototype but alone reduces the number of StructureIDs create for about:blank by 10, from 142 to 132. * kjs/JSGlobalObject.cpp: (JSC::JSGlobalObject::reset): * kjs/JSObject.cpp: (JSC::JSObject::putDirectFunctionWithoutTransition): * kjs/JSObject.h: (JSC::JSObject::putDirectWithoutTransition): * kjs/ObjectPrototype.cpp: (JSC::ObjectPrototype::ObjectPrototype): * kjs/ObjectPrototype.h: * kjs/StructureID.cpp: (JSC::StructureID::addPropertyWithoutTransition): * kjs/StructureID.h: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@37645 268f45cc-cd09-0410-ab3c-d52691b4dbfc
