[PATCH] D12350: FastISel: Avoid adding a successor block twice for degenerate IR.

[Chad Rosier via llvm-commits]

Matthias,
Juergen is probably more familiar with FastISel than I these days, but the patch itself looks reasonable.  I'll let Juergen give the final LGTM, however.

Is the degenerate IR a result of not running the optimizers (i.e., using -O0)?  I'm just trying to understand how we arrived at this situation to determine if this really is the correct place to address the problem.
