New issue 3234 by [email protected]: Octane2.1/CodeLoad regression; r19383 & r19384 probably contributed around 1 - 1.5 %
http://code.google.com/p/v8/issues/detail?id=3234

Background: Gradual 5% regression on code load (15000 -> 14200) between r18426 and r20201 (~1800 revisions), reproes locally on x64.

It looks like these commits might contribute to it (around 1 - 1.5% together):

    Don't mix handler flags into regular flag computation.

Pass in the handler kind to IC computation rather than extracting it from the handler.
