[PATCH] D61887: [SelectionDAG] computeKnownBits - support constant pool values from target

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 200921.
RKSimon added a comment.

Use isNON_EXTLoad and pull out the Constant so we could add support for EXTLoad cases in the future if we see the need.
