[Hexagon] Add HVX support for ISD::SMAX/SMIN/UMAX/UMIN instead of custom dag patterns

Authored by RKSimon on Nov 26 2020, 3:39 AM.



Followup to D92112 now that I've learnt about hvx type splitting.

This is some necessary cleanup work for min/max ops to eventually help us move the add/sub sat patterns into DAGCombine - D91876.
