An automated rewrite will add concrete type assertions after a test of n.Op(), when n can be safely type-asserted (meaning, n is not reassigned a different type, n is not reassigned and then used outside the scope of the type assertion, and so on). This sequence of CLs handles the code that the automated rewrite does not: adding specific types to function arguments, adjusting code not to call n.Left() etc when n may have multiple representations, and so on. This CL focuses on noder.go. Passes buildall w/ toolstash -cmp.
