%%% Tests whether calling module_info from the same module works.
%%% This seems trivial, but the problem is that the module_info/[0,1]
%%% functions that the BEAM file contains used to be dummy functions
%%% containing crap. So, these functions could not be used for
%%% compilation to native code and the functions that the BEAM loader
%%% generates should have been used instead. This was a HiPE bug
%%% reported by Dan Wallin.
