Reviewed by Darin Adler.

Switch to passing around "const Attribute&" instead of "Attribute*" wherever possible.
This helps enforce the constness and non-nullity of these arguments at compile time.

Also renamed 'attr' to 'attribute' in the touched code. Attr and Attribute are two
different classes, so having "Attribute attr" just looks wrong.
