[PATCH] D20126: [ScheduleDAG] Make sure that addVRegUseDeps is called on subreg defs

[Matthias Braun via llvm-commits]

MatzeB added a comment.

That is the case I just discussed with Andy. We believe that the current code is fine because we get the output dependence edge anyway. So for now I added a comment to document this fact and avoid creating extra edges.
