Sanjay Patel 2c5b9e376b [ARM] don't transform an add(ext Cond), C to select unless there's a setcc of the condition ... The transform in question claims to be doing: // fold (add (select cc, 0, c), x) -> (select cc, x, (add, x, c)) ...starting in PerformADDCombineWithOperands(), but it wasn't actually checking for a setcc node for the sext/zext patterns. This is exactly the opposite of a transform I'd like to add to DAGCombiner's foldSelectOfConstants(), so I was seeing infinite loops with my draft of a patch applied. The changes in select_const.ll look positive (less instructions). The change in arm-and-tst-peephole.ll is unrelated. We're changing the input IR in that test to preserve the intent of the test, but that's not affected by this code change.
