Duncan P. N. Exon Smith 41cf73ce16 CodeGen: Don't dereference end() in MachineBasicBlock::CorrectExtraCFGEdges ...

The current MachineBasicBlock might be the last block, so FallThru may
be past the end().  Use getNextNode(), which will convert to nullptr,
rather than &*++, which is invalid if we reach the end().
