Subject: add definemethod/definesmethod insn.

* insns.def: add definemethod and definesmethod (singleton method)
  instructions. Old YARV contains these instructions, but it is moved
  to methods of FrozenCore class because remove number of instructions
  can improve performance for some techniques (static stack caching
  and so on). However, we don't employ these technique and it is hard
  to optimize/analysis definition sequence. So I decide to introduce
  them (and remove definition methods). `putiseq` insn is also removed.

* vm_method.c (rb_scope_visibility_get): renamed to
  `vm_scope_visibility_get()` and make it accept `ec`.
  Same for `vm_scope_module_func_check()`.
  These fixes are result of refactoring `vm_define_method`.

* vm_insnhelper.c (rb_vm_get_cref): renamed to `vm_get_cref`
  because of consistency with other functions.
