Zip from the script / cpp file produced by Clang.

Possible culprit:

http://llvm.org/viewvc/llvm-project?view=revision&revision=279314

I'm attaching the original files now, will see if I can reduce it.

Error:

clang-4.0:

llvm::ilist_iterator<NodeTy>::operator*() const [with NodeTy =
llvm::MachineInstr; llvm::ilist_iterator<NodeTy>::reference =
llvm::MachineInstr&]: Assertion `!NodePtr->isKnownSentinel()' failed.
