  -----------
  [DAGCombiner] Teach SearchForAndLoads to handle an AND with 2 constant operands. (#142062)

If opaque constants are involved we can have an AND with 2 constant
operands that hasn't been simplified. If this is the case, we need
to modify at least one of the constants if it is out of range.
    
Fixes #142004
