Feature #11146

Updated by nobu (Nobuyoshi Nakada) almost 9 years ago

Even miniruby creates one generic ivar (plain "ruby" creates 9), 
 so there's no point in lazily allocating the table and increasing 
 lines of code. 

 I'll commit in a few days unless there's objections. 

 I dumped generic ivar counts with the following trivial patch:
