[Nouveau] [PATCH v2] nv50/ir: optimize shl(a, 0) to a

helps two alien isolation shaders shader-db: total instructions in shared programs : 4251497 -> 4251494 (-0.00%) total gprs used in shared programs: 513962 -> 513962 (0.00%) total local used in shared programs : 29797 -> 29797 (0.00%) total bytes used in shared programs : 38960264 ->
