[PATCH] D87867: [NFC][ScheduleDAG] Remove unused EntrySU SUnit

[Hendrik Greving via Phabricator via llvm-commits]

hgreving added a comment.

Our backend is using EntrySU the same way as described by another poster above: to add top edges to adjust for clearances to the basic block entry. When removing this, we need to add our own EntrySU, but this becomes tricky because the scheduler will try to schedule it and release the node. I think it does make sense to keep EntrySU in-tree. Thanks for that.
