Add GlobalDSGraph -- a common graph that holds externally visible nodes.

Print globals graph after either the BU or the TD pass.

This file implements the top-down propagation pass for data structure graphs.

Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.
