With verbopse mode (-w), the interpreter shows a warning if
a block is passed to a method which does not use the given block.

Warning on:

* the invoked method is written in C
* the invoked method is not `initialize`
* not invoked with `super`
* the first time on the call-site with the invoked method
  (`obj.foo{}` will be warned once if `foo` is same method)

for `test-bundled-gems`.

to @__passed__, @@__current__.
@passed is redefined in a few test suites, and this could lead to bugs.

Also rename @options (Runner#options) to @__runner_options__, which is
only used in make test-tool anyway.
