I took a look at your libclc fix, and I realized that we can't use address
space qualifiers in common code, because addrspace(1) may not mean global
address space on all targets.

I think you might find that the optimizers are good enough to turn a .cl
implementation into optimal code, but if not we may be have to move the LLVM IR
implementations into target specific code.
