Simon Pilgrim 791040cd8b [DAG] LowerMINMAX - move default expansion to generic TargetLowering::expandIntMINMAX ...

This is part of the discussion on D91876 about trying to reduce custom lowering of MIN/MAX ops on older SSE targets - if we can improve generic vector expansion we should be able to relax the limitations in SelectionDAGBuilder when it will let MIN/MAX ops be generated, and avoid having to flag so many ops as 'custom'.
