  Log Message:
  -----------
  [DAG] Legalize umin(x,y) -> sub(x,usubsat(x,y)) and umax(x,y) -> add(x,usubsat(y,x)) iff usubsat is legal

If usubsat() is legal, this is likely to result in smaller codegen expansion than the default cmp+select codegen expansion.

Allows us to move the x86-specific lowering to the generic expansion code.
