No superclass method in ruby 2.1
Runing ruby 2.1 plus nobu's patch from issue 9315. Without the patch it segfaults.
Found this testing testing test-redef with ruby 2.1. Works on 2.0.0-p353 and fails on 2.1.0. When the replacement method calls the alias directly it works but when we fetch the method and #call it the mixin can't super up.

Seems to be fine on ruby_2_1, after r44410 (merging r44380).
I confirmed NoMethodError is raised on 2.1.0 (r44340) and not on ruby_2_1 (r44443).
But 'ruby -v' of this ticket is revision 44422 (> 44410).
Really test.rb fails on r44422? I can't figure out what happens.
