Add testcase for locals identified with FUNCTION::VAR syntax.

Add testcase for locals identified with FUNCTION::VAR syntax.

This test stops inside a recursive function after a few levels of recursion,
goes up some frames, and then accesses a local variable with 'print foo::val'
rather than the usual 'print val' to see if the former pays attention to the
selected frame.
