[PATCH] D41539: [CodeGen] Decorate aggregate accesses with TBAA tags

Sure, but since it is not a trivial change we could first replace 'tbaa.struct' with 'tbaa' and then decide how to attach multiple TBAA tags to an instruction. I didn't think enough about it, but one way to do that is to have different kinds of TBAA tags for read and write accesses, in which case we could re-purpose the 'tbaa.struct' tag slot.
