We're doing pretty good on this but Crankshaft is about 20-30% faster. According to VTune, we spend most of our time (54%) in lin_solve(), and 50% of that time is spent on line 150 (which is a huge array access expression inside a triply nested loop).

18% of our time is spent in ic-name, so bug 753158 should be a decent win.

The difference here is now 3-5% so closing for now.
