Description Filip Pizlo 2012-03-08 01:05:44 PST 
This will increase coverage, help catch bugs, and help to find new performance optimization opportunities.

Currently doing so is neutral except in V8 run using the SunSpider harness, because of a slow-down in raytrace.  This appears to just be because of increase compilation time, with raytrace then running for such a short time that it never benefits from the optimized code.  We should explore ways of mitigating such slow-downs, but given that this change is neutral for V8 in the V8 harness it's not a huge priority.
