* eval.c (svalue_to_avalue): need to splat but no error.

* eval.c: new macros - YIELD_CALL, YIELD_VALUES.

* eval.c (rb_yield_values): specify YIELD_VALUES.

* eval.c (rb_yield_0): use new macros.

* eval.c (proc_invoke): slightly modified to separate YIELD_CALL
  and YIELD_VALUES from YIELD_ARY_ARGS.

* object.c (Init_Object): add nil.to_splat => [].
