b008d99b11 Ensure that all descriptors have a valid enumeration index, and replace NextEnumIndex with LastAdded. 
The LastAdded points to the descriptor that was last added to the array. From the descriptor we can deduce the NextEnumerationIndex. This allows us to quickly find the property that we are transitioning to, which is necessary for transition-intensive code, eg JSON parsing.

45419ee145 Swap bitfield3 and backpointer. 
Bitfield3 now has its own field, while the backpointer shares the field with the descriptor array; which will become the transition array.

2b574ef580 Promoting elements transitions to their own field. 
This is a first step towards separating all transitions from the property descriptions. If we link the property descriptions from the transition object, this will in allow the descriptor array (property descriptions) to become immutable.

6703dddac4 Support fast case for-in in Crankshaft. 
Only JSObject enumerables with enum cache (fast case properties, no interceptors, no enumerable properties on the prototype) are supported.

HLoadKeyedGeneric with keys produced by for-in enumeration are recognized and rewritten into direct property load by index. For this enum-cache was extended to store property indices in a separate array (see handles.cc).

New hydrogen instructions:

- HForInPrepareMap: checks for-in fast case preconditions and returns map that contains enum-cache;
- HForInCacheArray: extracts enum-cache array from the map;
- HCheckMapValue: map check with HValue map instead of immediate;
- HLoadFieldByIndex: load fast property by it's index, positive indexes denote in-object properties, negative - out of object properties;

Changed hydrogen instructions:

- HLoadKeyedFastElement: added hole check suppression for loads from internal FixedArrays that are knows to have no holes inside.

e49d533b50 Reapply "Add a level of indirection to exception handler addresses." 
Original commit message:

Add a level of indirection to exception handler addresses.

To support deoptimization of exception handlers, the handler address in the
stack is converted to a pair of code object and an index into a separate
table of code offsets.  The index part is invariant under deoptimization.
The index is packed into the handler state field so that handler size does
not change.
