  Log Message:
  GISel/Combiner: maintain created instructions in a SetVector

This is not a correctness fix because the set is only used for debug
output. However, it helps avoid noise when looking at diffs between
compiler runs.

The set is only maintained with debug output enabled, so the added cost
should be acceptable.
