error.c: super in method_missing

Browse source 
* error.c (nometh_err_initialize): do not shirtcut rb_call_super,
  to push proper control frame.  [ruby-dev:50522] [Bug #14670]

* error.c (rb_nomethod_err_new): allocate and initialize a new
  NoMethodError instance.

* vm_eval.c (rb_make_no_method_exception): create a new exception
  instance directly without method calls, to prevent influence of
  ruby level method definitions, which can cause an unpredictable
  behavior, e.g., infinite recursion.
