Struct-path aware TBAA: uniformize scalar tag and path tag. For struct-path aware TBAA, we used to use scalar type node as the scalar tag, which has an incompatible format with the struct path tag. We now use the same format: base type, access type and offset. We also uniformize the scalar type node and the struct type node: name, a list of pairs (offset + pointer to MDNode). For scalar type, we have a single pair. These are to make implementaiton of aliasing rules easier. llvm-svn: 179335
