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

[Huihui Zhang via Phabricator via llvm-commits]

huihuiz added a comment.

This problem caused assertion on: Assertion `BlockToChain[&MBB]->UnscheduledPredecessors == 0 && "expect unschedPred to be 0\n"' failed.

My apologies for not able to get a test case here. I try really hard to reduce a test case, but failed.
