//1) cross-thread inline data will be put into R1, but if kernel uses local ids, then cross-thread should be put further back
//so whenever local ids are driver or hw generated, reserve space by setting right values for emitLocalIds
//2) Auto-generation of local ids should be possible, when in fact local ids are used
