.13x Sun Spider regression with TI disabled at runtime
SunSpider 0.9.1 in-browser: Jun 6 m-c nightly: 200.7 Jun 7 TI nightly: 227.2

I think these numbers were with a stale JM build (JM Win7 nightlies were not being generated for a couple months). With a Win7 build from a couple weeks ago, I get a 4% SS regression with inference disabled. This can be improved to a 2% or so regression by disabling inference at compile time, but doing much better than that will be very hard --- SS is so short running that it spends a lot of time in the VM, and a few of the non-removable TI-disabled changes (object layout changes, extra dereference for obj->proto) slow down the VM some while improving JIT perf.
I'm not seeing a significant difference on Windows right now, although the times I get are 10% slower in general. I'll have to do some checks to see if that is a recent regression or if it's just running slower today.
TI has been enabled in many stable builds and Ion is even disabled without it.
