[ValueTracking] enhance matching of umin/umax with 'not' operands
The cmyk test is based on the known regression that resulted from:
rGf2fbdf76d8d0
This improves on the equivalent signed min/max change:
rG867f0c3c4d8c
The underlying icmp equivalence is:
~X pred ~Y --> Y pred X
For an icmp with constant, canonicalization results in a swapped pred:
~X < C --> X > ~C
