Sanjay Patel df3286259b [DAGCombiner] don't try to partially reduce add-with-overflow ops ... This transform was added with D58874, but there were no tests for overflow ops. We need to change this one way or another because it can crash as shown in: https://llvm.org/PR51238 Note that if there are no uses of an overflow op's bool overflow result, we reduce it to a regular math op, so we continue to fold that case either way. If we have uses of both the math and the overflow bool, then we are likely not saving anything by creating an independent sub instruction as seen in the test diffs here. This patch makes the behavior in SDAG consistent with what we do in instcombine AFAICT.
