WIP since I need to think more about the best way to fix this, but here's an example that trips the assertion.  Very relevant is the statement in `llvm::SplitCriticalEdge`:

  NewBI->setDebugLoc(TI->getDebugLoc());

where the synthesized block gets its debug info from the predecessor (which can be none-by accident).

Also, this is forked from https://reviews.llvm.org/D100137.
