[PATCH] D41136: [EarlyCSE] recognize commuted and swapped variants of min/max as equivalent (PR35642)

Patch updated:
Use ValueTracking's matchSelectPattern() rather than pattern matchers for min/max. This:

1. Makes the patch smaller
2. Catches more cases (extra test added)
3. Allows follow-up patches to enable abs() and FP min/max more easily
