fourthTier: AbstractInterpreter should explicitly ask AbstractState to create new AbstractValues for newly born nodes https://bugs.webkit.org/show_bug.cgi?id=118880 Reviewed by Sam Weinig. It should be possible to have an AbstractState that is backed by a HashMap. But to do this, the AbstractInterpreter should explicitly ask for new nodes to be added to the map, since otherwise the idiom of getting a reference to the AbstractValue returned by forNode() would cause really subtle memory corruption bugs. * dfg/DFGAbstractInterpreterInlines.h: (JSC::DFG::::executeEffects): * dfg/DFGInPlaceAbstractState.h: (JSC::DFG::InPlaceAbstractState::createValueForNode): (InPlaceAbstractState): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@153283 268f45cc-cd09-0410-ab3c-d52691b4dbfc
