* method.h: introduce new method type VM_METHOD_TYPE_CFUNC_FAST.
This method is similar to VM_METHOD_TYPE_CFUNC methods, but
called cfunc without building new frame (does not push new control
frame). If error is occured in cfunc, the backtrace only shows
caller frame and upper.
This kind of methods can be added by rb_define_method_fast().
This feature is similar to specialized instructions (opt_plus, etc),
but more flexible (but a bit slower).
* class.c (rb_define_method_fast): added.
Maybe it will be renamed soon.
* vm_insnhelper.c (vm_call_method): support method type
VM_METHOD_TYPE_CFUNC_FAST.
* proc.c (rb_method_entry_arity): catch up new method type.
* vm_method.c (rb_add_method_cfunc_fast): added.
