Fixed version (ground truth):

 * @param node the node we are computing heap reaching defs for
 * @param ir IR for the node
 * @param pa governing pointer analysis
 * @param mod the set of heap locations which may be written (transitively) by this node. These are logically return values in the SDG.
 * @param statements the statements whose def-use are considered interesting
 * @param exclusions heap locations that should be excluded from data dependence tracking
