Ross McIlroy d9828e4553 [Turboprop] Allow removal of multiple unreachable blocks that merge.
The scheduler could schedule unreachable nodes on two basic blocks that
later merge. Update DCHECK in graph-assembler's basic block updater to
only check for the self-containedness of unreachable basic blocks
removed from the schedule after all the blocks have been re-written to
allow for this case.
