[PATCH] D70030: [MachineBlockPlacement] Update UnscheduledPredecessors when tail duplicate delete a block.

[Huihui Zhang via Phabricator via llvm-commits]

huihuiz added a comment.

Actually fillWorkLists is not called for the deleted BB, but the MBBs of BBChain. The BB is deleted.
Here BBChain will have an unreleased UnscheduledPredecessors counter, when calling fillWorkLists for any MBBs within BBChain, this assertion will happen.
