http://build.chromium.org/f/chromium/perf/mac-release-10.6-webkit-latest/moz/report.html?rev=168757&graph=times&history&history=50
It's almost certainly not something on the Chromium side: http://build.chromium.org/f/chromium/perf/dashboard/ui/changelog.html?url=/trunk/src&mode=html&range=168480:168481
Which leaves the following WebKit regression range: http://trac.webkit.org/log/?verbose=on&rev=135087&stop_rev=135083
It seems it must be one of the 3 V8 changes in that range.

The V8 changes in that range aren't supposed to change the generated code at all. If there's a behavior change, that's likely a mistake.
