[PATCH] D32555: [SelectionDAG] Use various APInt methods to reduce temporary APInt creation

[Craig Topper via Phabricator via llvm-commits]

craig.topper created this revision.

This patch uses various APInt methods to reduce the number of temporary APInts. These were all found while working through converting SelectionDAG's computeKnownBits to also use the KnownBits struct recently added to the ValueTracking version.
