Recognize nested MIN-MAX operations. Rationale: Prior to this CL, select optimizer and instruction simplifier were unable to deal with more than one select. This CLs improves MIN-MAX recognition by allowing select diamonds to nest deeper and by recognizing constant clipping operations. This yields better optimizable code, as shown with more saturation idioms. Bug: b/74026074 Test: test-art-host,target Change-Id: I8a616a19475f1ae87c2b5210afc76b14265bd571
