nir/algebraic: optimize iand/ior of (n)eq zero when umax/umin not available
Before 8e1b75b330954a ("nir/algebraic: optimize iand/ior of (n)eq zero") this
optimization didn't need the use of umax/umin. VC4 HW supports only signed
integer max/min operations.
lower_umin and lower_umax are added to allow enabling previous optimizations
behaviour for this cases.
