Subject: [PATCH] vc4: Enable lower_umax and lower_umin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VC4 doesn't have support for UMAX and UMIN integer operations. So
we should avoid algebraic optimizations that generate umax/umin ops.

Fixes: 8e1b75b330954a ("nir/algebraic: optimize iand/ior of (n)eq zero")
