In Ruby 3.2 or later, a nested constant access like `Foo::Bar::Baz` is
compiled to one instruction by the optimization ruby/ruby#6187

We try to spot which sub-node caues a NameError in question based on the
constant name. We will give up if the same constant name is accessed in
a nested access (`Foo::Foo`).

Fixes #31
