    Directly resolve range_of_stmt dependencies.

    All ranger API entries eventually call range_of_stmt to ensure there is an
    initial global value to work with.  This can cause very deep call chains
when
    satisfied via the normal API.  Instead, push any dependencies onto a stack
    and evaluate them in a depth first manner, mirroring what would have
happened
    via the normal API calls.
