Error in index type inference.

 def bar(foo):
     qux = foo
     quux = foo[qux.baz]

The error message:

       $ cython bar.py

       Error compiling Cython file:

The problem was that the indexing operator inference was changed to depend on the index type, but its type_dependencies method wasn't updated to reflect this.
