55e924c595 Fix CNLT regression. 
This happens when a map A with no descriptors in fast_holey_elements
mode first gets some properties, making it share descriptor arrays with
a map B to which it transitions. Then map A transitions elements kind to
dictionary_elements in map C. C stores the empty_descriptor_array in its
own transition array. When adding a property to C, C transitions to D
and shares the descriptors. If D dies, a CNLT clears the transition
array of C, making the descriptor array of A (and thus also of B) shine
through. If a property is now added to an object in state C, it'll inherit
all the properties of A (and B). If those properties had high field indices,
we do not have a large enough backing store for the single newly added
property, and we'll write out of bounds.

83fc4205f6 Fixed compound/count operations with getter-only accessor properties. 
The underlying problem is that for compound/count operations we use the *load*
type feedback for storing, too. For normal properties this doesn't matter, but
for accessor properties we should better use the *store* type feedback, which
would be available, too. This consistent feedback usage could be guaranteed if
we removed the heavy copy-n-paste in the crankshaft code generation for
compound/count operations and assignments/property loads.

To be on the safe side, we postpone this refactoring and do a quick and easily
mergeable fix.
