Looking at bugzilla PR11087, I'd like to conditionalise a transformation in
ARMIselLowering.cpp based on whether we're compiling for codesize or


-Os doesn't actually exist for llc, and I can't see an obvious place where
that condition would be set. Where do we specify if we're optimizing for
codesize or performance?
