Using OrderedInstructions::dominates as comparator for instructions in BBs without dominance relation can cause a non-deterministic order between such instructions. That in turn can cause us to materialize copies in a non-deterministic order. While this does not effect correctness, it causes some minor non-determinism in the final generated code, because values have slightly different labels. Without this patch, running -print-predicateinfo on a reasonably large module produces slightly different output on each run. This patch uses the dominator trees DFSInNum to order instruction from different BBs, which should enforce a deterministic ordering and guarantee that dominated instructions come after the instructions that dominate them.
