Bardia Mahjour 2dd82a1c04 [DDG] Data Dependence Graph - Topological Sort (Memory Leak Fix) 
Summary:
This fixes the memory leak in bec37c3fc7
and re-delivers the reverted patch.
In this patch the DDG DAG is sorted topologically to put the
nodes in the graph in the order that would satisfy all
dependencies. This helps transformations that would like to
generate code based on the DDG. Since the DDG is a DAG a
reverse-post-order traversal would give us the topological
ordering. This patch also sorts the basic blocks passed to
the builder based on program order to ensure that the
dependencies are computed in the correct direction.
