Fix for <rdar://problem/6129678>
REGRESSION (Safari 3-4): Local variable not accessible from Dashcode console or variables view

Iterating the properties of activation objects accessed through the WebKit debugging
APIs was broken by forced conversion of JSActivation to the global object. To fix this,
we use a proxy activation object that acts more like a normal JSObject.

• debugger/DebuggerActivation.cpp: Added. (JSC::DebuggerActivation::DebuggerActivation): (JSC::DebuggerActivation::mark): (JSC::DebuggerActivation::className): (JSC::DebuggerActivation::getOwnPropertySlot): (JSC::DebuggerActivation::put): (JSC::DebuggerActivation::putWithAttributes): (JSC::DebuggerActivation::deleteProperty): (JSC::DebuggerActivation::getPropertyNames): (JSC::DebuggerActivation::getPropertyAttributes): (JSC::DebuggerActivation::defineGetter): (JSC::DebuggerActivation::defineSetter): (JSC::DebuggerActivation::lookupGetter): (JSC::DebuggerActivation::lookupSetter):
• debugger/DebuggerActivation.h: Added. Proxy JSActivation object for Debugging.

• runtime/JSActivation.h: (JSC::JSActivation::isActivationObject): Added.
• runtime/JSObject.h: (JSC::JSObject::isActivationObject): Added.
