[PATCH] D47917: [ARM] Lower llvm.ctlz.i32 to a libcall when clz is not available.

I'm not too familiar with ARM/Thumb codegen. Add the extra RUN with the current output, so we can see the difference?

Should there also be a test to demonstrate the difference between regular codegen and codegen with the optsize/minsize attribute?
