Message:

• oops, checked in big regression instead of 5% speedup

• kjs/function.cpp: (ActivationImp::ActivationImp): Make a marking list, not a refing list.

• a cut at the sparse array implementation

• kjs/array_instance.h: Keep storageLength separate from length.
• kjs/array_object.cpp: (ArrayInstanceImp::ArrayInstanceImp): Start with storageLength == length. (ArrayInstanceImp::get): Check against storage length. (ArrayInstanceImp::put): Ditto. (ArrayInstanceImp::hasProperty): Ditto. (ArrayInstanceImp::deleteProperty): Ditto. (ArrayInstanceImp::setLength): Only enlarge storage length up to a cutoff. (ArrayInstanceImp::mark): Use storageLength. (ArrayInstanceImp::pushUndefinedObjectsToEnd): Added FIXME.
