Boris Zbarsky f890715ffc Bug 656197 part 1. Remove the generic attr preparsing mechanism from BeforeSetAttr and just preparse class attributes directly in the one place that needs to do it. r=smaug
This removes the requirement that BeforeSetAttr comes before AttributeWillChange
(which needs the preparsed new value).
