Description

Allow removal of obsolete map checks after transitions. This allows side effect dominator tracking to remove map checks that are dominated by a single HStoreNamedField that performs a transition on the same object. A similar trick could be applied to HAllocateObject. R=jkummerow@chromium.org Committed: http://code.google.com/p/v8/source/detail?r=13488
