Robohornet's reflow test spends 2% of total time in ScrollbarThemeMac::registerScrollbar calling NSClassFromString("ScrollBarImp")

http://www.robohornet.org/tests/offsetreflow.html

An easy fix would be to cache the class pointer, since it's unlikely to change. :)

Unclear how much (if at all) this affects real web content.

Actually, I don't think it's the ClassFromString lookup.  This may just be a dupe of bug 98622.
