Integer add/sub can be implemented as either an add or a mul instruction but we always emit them as add instructions at VIR level. We can use this flexibility to improve our QPU scheduling so we can be more effective at instruction merging by converting these to mul instructions when we are attempting to merge them with another add instruction. total instructions in shared programs: 13721549 -> 13691004 (-0.22%) instructions in affected programs: 3340493 -> 3309948 (-0.91%) helped: 12805 HURT: 1656 Instructions are helped. total max-temps in shared programs: 2319528 -> 2319317 (<.01%) max-temps in affected programs: 5285 -> 5074 (-3.99%) helped: 195 HURT: 3 Max-temps are helped. total sfu-stalls in shared programs: 31616 -> 31752 (0.43%) sfu-stalls in affected programs: 469 -> 605 (29.00%) helped: 52 HURT: 161 Sfu-stalls are HURT. total inst-and-stalls in shared programs: 13753165 -> 13722756 (-0.22%) inst-and-stalls in affected programs: 3340383 -> 3309974 (-0.91%) helped: 12782 HURT: 1666 Inst-and-stalls are helped.
