`th` -> `ec` for method management functions.

* vm_eval.c: `th` -> `ec` for the following functions:
  * check_funcall_respond_to
  * check_funcall_callable
  * check_funcall_missing
  * rb_method_call_status

* vm_method.c: ditto.
  * call_method_entry
  * basic_obj_respond_to_missing
  * basic_obj_respond_to
  * vm_respond_to

* vm_eval.c (stack_check): accepts `ec` instead of `th`.
