Testcase attached; llc crashes with:

Assertion failed: (!isa<IndirectBrInst>(TI) && "Cannot split critical edge from
IndirectBrInst"), function SplitCriticalEdge, file
/Volumes/storage/llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp, line 175.

Not sure anyone is actually likely to hit this in practice, but it seems
possible.
