[PATCH] D40176: [CodeGen] Collect information about sizes of accesses and access types for TBAA

[Ivan Kosarev via Phabricator via cfe-commits]

kosarev added a project: clang.

The information about access and type sizes is necessary for producing TBAA metadata in the new size-aware format. With this patch, https://reviews.llvm.org/D39955 and https://reviews.llvm.org/D39956 in place we should be able to change CodeGenTBAA::createScalarTypeNode() and CodeGenTBAA::getBaseTypeInfo() to generate metadata in the new format under the -new-struct-path-tbaa command-line option. For now, this new information remains unused.
