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.
