[PATCH] D47831: [DAGCombiner] Recognize more patterns for ABS

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

While I remember ValueTracking matches SPF_ABS/SPF_NABS selection style patterns - but SelectionDAGBuilder::visitSelect still doesn't support SPF_ABS/SPF_NABS which prevents it being used
