[PATCH] D41563: [Transforms] Propagate TBAA info in SROA

[Ivan Kosarev via Phabricator via llvm-commits]

Now that we have the new TBAA metadata format that is capable of representing accesses to aggregates, we can propagate TBAA access tags from memory setting and transferring intrinsics to load and store instructions and vice versa.

Since SROA produces lots of new loads and stores on optimized builds, this change significantly decreases the share of undecorated memory accesses on such builds.
