bugpoint reduced test case

The attached test case now crashes with this assertion:

llc:
/nfs2/hfinkel/src/llvm-trunk-writable/include/llvm/CodeGen/SlotIndexes.h:410:
llvm::SlotIndex llvm::SlotIndexes::getInstructionIndex(const
llvm::MachineInstr*) const: Assertion `itr != mi2iMap.end() && "Instruction not
found in maps."' failed.

I believe this may be related to "r180193 - MI Sched: eliminate local vreg
copies.".

Run with -mtriple=powerpc64-unknown-linux-gnu -mcpu=ppc64 -enable-misched</pre>
