rG0e3e242209c7: [BFI] Fix missed BFI updates in MachineSink.

Summary

This prevents BFI queries on new blocks (from
MachineSinking::GetAllSortedSuccessors) and fixes a bunch of assert failures
under -check-bfi-unknown-block-queries=true.

Add a test case (which would fail under the validation option) without the fix?

Around 400 tests fail under this flag without the fix. One of them is this simple (existing) machine sink test. Would it be enough? Or would you like me to add another one like that?
