Extended Description

The attached testcase verifies OK, but the code generator barfs on it:

$ opt -verify loops.ll -disable-output
$ llc loops.ll
llc: llvm/lib/Transforms/Utils/BreakCriticalEdges.cpp:182: llvm::BasicBlock* llvm::SplitCriticalEdge(llvm::TerminatorInst*, unsigned int, llvm::Pass*, bool): Assertion `!DestBB->isLandingPad() && "Cannot split critical edge to a landing pad block!"' failed.

This one might have been the same problem as llvm/llvm-bugzilla-archive#10733 . It passes for me now. Please check with the original test case. :-)
