Ross McIlroy 66e1c84d77 [TurboProp] Fully remove successors from schedule on unreachable. ... Fully remove the successor blocks when effect-control-linearization reaches an unreachable node and is maintaining the schedule. Previously we just updated the current_block_'s successor and removed any unreachable predecessors from end, however if the current_block_ is not an original block in the schedule, but a new one added due to control flow from effect control linearization lowering, the removed successor blocks could still be re-connected to the end block when they were lowered. Instead, entirely remove these unreachable blocks from the predecessor / successor chains, and have the effect-control-linearizer avoid lowering these blocks entirely.
