Reason for revert: Bug: failing to use write barrier when writing code entry into closure. Original issue's description: > Reland of Type Feedback Vector lives in the closure > > (Fixed a bug found by nosnap builds.) > > We get less "pollution" of type feedback if we have one vector per native > context, rather than one for the whole system. This CL moves the vector > appropriately. > > We rely more heavily on the Optimized Code Map in the SharedFunctionInfo. The > vector actually lives in the first slot of the literals array (indeed there is > great commonality between those arrays, they can be thought of as the same > thing). So we make greater effort to ensure there is a valid literals array > after compilation. > > This meant, for performance reasons, that we needed to extend > FastNewClosureStub to support creating closures with literals. And ultimately, > it drove us to move the optimized code map lookup out of FastNewClosureStub > and into the compile lazy builtin. > > The heap change is trivial so I TBR Hannes for it... > > TBR=hpayer@chromium.org > BUG= > > Committed: https://crrev.com/d984b3b0ce91e55800f5323b4bb32a06f8a5aab1 > Cr-Commit-Position: refs/heads/master@{#33548} TBR=bmeurer@chromium.org,yangguo@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
