• two simple speed improvements for a 3% speed gain

• JavaScriptCore.xcodeproj/project.pbxproj: turn on -fstrict-aliasing

• kjs/scope_chain.h: (KJS::ScopeChainIterator::ScopeChainIterator): Add a scope chain iterator so you can walk a scope chain without having to make a copy that you then mutate. (KJS::ScopeChainIterator::operator*): standard iterator operation (KJS::ScopeChainIterator::operator->): ditto (KJS::ScopeChainIterator::operator++): ditto (KJS::ScopeChainIterator::operator==): ditto (KJS::ScopeChainIterator::operator!=): ditto (KJS::ScopeChain::begin): Iterator for the top of the scope chain (KJS::ScopeChain::end): Iterator for one past the bottom (i.e. null)
• kjs/nodes.cpp: (ResolveNode::evaluate): Use scope chain iterator instead of copying a scope chain and then modifying the copy (ResolveNode::evaluateReference): ditto (FunctionCallResolveNode::evaluate): ditto (AssignResolveNode::evaluate): ditto
