On my machine, the getter/setter change caused a regression in JavaScript iBench speed from 1980ms or so to ~2150ms. After the fix for 6083, it is down to 2020. That's way better, but still a regression.
Some of the suggestions in bug 6083 might help.

Comment on attachment 5509 [details] patch that gets a bunch of speedups by passing this stuff for activation objects Looks good. You missed an ending newline in the very last file in this patch.
Cc'd Maks, this has some interesting general speedups along the lines of what we talked about as well as fixing the slowdown from the getter/setter change.
