Because this is checking for VALU instructions -- VALU instructions being those that a user would expect (e.g. V_ADD). But, we have an annoying problem where the DMA instructions are also VALU so they get picked up here, and we added the !mayLoadOrStore check. Really we want to ensure we are not accidentally picking up the LDSDMA instructions
