One minor fix, but otherwise LGTM



================
Comment at: lib/CodeGen/MachineBlockPlacement.cpp:1680
+              !PrevBB->canFallThrough()) &&
+             "Precondition violated!");
+      Cond.clear();
----------------
Can you make the assert comment here more descriptive, something like:
"Unexpected block with un-analyzable fallthrough detected."
