  -----------
  [DAG] Fix typo in i64/i128 abdu/abds tests

I'd incorrectly swapped the operands in some of the "cmp" test patterns when I changed the condition code

  Log Message:
  -----------
  [DAG] visitSELECT - add "select usubo(x, y).overflow, (sub y, x), (usubo x, y) -> abdu(x, y)" fold (and neg equivalent)

Handle cases where CGP has merged the CMP+SUB into a USUBO node - improves a few outstanding niggles from #100810
