Jim Ingham e4ce44197c Switch over to using object_getClass to get the class of an object. Previously we were
directly accessing the isa pointer of a class object to get its meta-class, but the isa
pointers are not simple pointers on arm64, so this would cause the stepping to fail.
object_getClass does whatever magic needs doing in this case.
