Functions
static SDValue	wrapAddr64Rsrc (SelectionDAG *DAG, SDLoc DL, SDValue Ptr)
static bool	isLegalMUBUFImmOffset (const ConstantSDNode *Imm)
static SDValue	buildRSRC (SelectionDAG *DAG, SDLoc DL, SDValue Ptr, uint32_t RsrcDword1, uint64_t RsrcDword2And3)
static SDValue	buildScratchRSRC (SelectionDAG *DAG, SDLoc DL, SDValue Ptr)
	Return a resource descriptor with the 'Add TID' bit enabled The TID (Thread ID) is multipled by the stride value (bits [61:48] of the resource descriptor) to create an offset, which is added to the resource ponter.
