Zsuper mutator

[dkubb]

This branch mutates zsuper nodes.

@mbj this causes one new mutation to be found in axiom-types, eg:

evil:Axiom::Types::Object.infer:/Users/dkubb/Dropbox/Home/Programming/open-source/axiom-types/lib/axiom/types/object.rb:25:4666a
@@ -1,4 +1,4 @@
 def self.infer(object)
-  ((super) || (infer_from_primitive_class(object)))
+  ((nil) || (infer_from_primitive_class(object)))
 end
(08/09)  88% - 1.11s

The part that I don't understand is why statement deletion didn't catch this in the first place? You'd think if it changed that to just infer_from_primitive_class(object) that it would have the same effect.

@dkubb Because statement deletion only works with begin and kwbegin nodes.
