[PATCH] D102255: [SelectionDAG] Generate scoped AA metadata when lowering memcpy.

[Michael Liao via Phabricator via llvm-commits]

hliao updated this revision to Diff 356804.

Rebase and resolve conflicts. Kindly PING for review.

BTW, the newly generated AA metadata only changes the alias checking results among loads/stores generated from this lowered memcpy. It won't change other alias checking result.
