LLVM IR to test

Consider the bytecode attached. I'm having:
$ ./llc bugpoint-reduced-simplified.ll -mcpu=cortex-a8
llvm::LiveInterval& llvm::LiveIntervals::getInterval(unsigned int): Assertion
`I != r2iMap_.end() && "Interval does not exist for register"' failed.

This is a fallout from REG_SEQUENCE stuff
