[CodeGen] Pass TBAA info along with lvalue base info everywhere

This patch addresses the rest of the cases where we pass lvalue
base info, but do not provide corresponding TBAA info.

This patch should not bring in any functional changes.

This is part of D38126 reworked to be a separate patch to make
reviewing easier.
