Have you considered moving ReplaceLLVMIntrinsicsPass earlier in the flow (before first LowerAddrSpaceCastPass) to get rid of those memcpy?
It might not be possible if memcpy gets generated by other passes (instcombine?).

Is clspv really able to deal with such a function to emit anything valid?
Maybe because it contains llvm.memcpy it works?

Yeah, the replace intrinsics pass seems prepared for this, as it looks at the function name containing "llvm.memcpy".
