This CL is a step towards removing ZoneObject's new operator without a Zone parameter, which uses Isolate::Current. For e.g. the bulletben benchmark, this CL reduces the number of calls to this new operator by roughly 120k, but we are still left with 780k calls from other sites...

With transitions in AccessorPairs, it is not enough to look at the PropertyType alone to decide whether we look at a property or not: For objects with JavaScript accessors, we have to look into the AccessorPair itself and see if one of its 2 parts is actually a JavaScript accessor. Therefore, a predicate with a PropertyType argument alone doesn't make sense anymore, we might need the associated value, too. Things are complicated by the fact that the holder in a LookupResult can be NULL, so we must be careful to retrieve its value only when it is really needed. To achieve the needed call-by-name semantics, a new Entry is introduced, which is basically a closure over a DescriptorArray and an index into this array (C++0x to the rescue!). GCC is clever enough to inline this class, so we pay no runtime penalty for this abstraction. It's all a bit ugly, but this is caused by the current structure of Descriptor, DescriptorArray and LookupResult: Things would be much easier if DescriptorArray were, well, an array of Descriptors, and LookupResult were a 'Maybe Descriptor' (in Haskell-terms).

As of dominators and retained sizes calculation take quite small time now comparing to the main passes, it is worth to exclude these from progress indicator.

This allows elements of the non-strict arguments object to be redefined with custom attributes and still maintain an alias into the context. Such a slow alias is maintained by placing a special marker into the dictionary backing store of the arguments object.
