* vm_insnhelper.c (vm_call_method, vm_call_cfunc): use original id instead of

  calling id when NODE_CFUNC or NODE_BMETHOD.
  fixes Bug #632 [ruby-core:19282].
* vm_eval.c (vm_call0, vm_call_super): ditto.
* vm_method.c (rb_add_method, rb_alias): store original id
  in nd_file field of NODE_METHOD.
* test/stringio/test_stringio.rb: add a test.
