* eval.c (massign): remove unnecessary array unpacking; it should

  be handled before massign() by svalue_to_mrhs().

* eval.c (svalue_to_mrhs): '*a = v' value conversion to avalue
  (i.e. [1] => [[1]], [1,2] => [1,2]).

* eval.c (rb_eval): use svalue_to_mrhs.

* eval.c (rb_yield_0): ditto.

* eval.c (proc_invoke): break from "Proc#yield" is legal.
