Ivan A. Kosarev f5f204679b [CodeGen] Generate TBAA info along with LValue base info ...

This patch enables explicit generation of TBAA information in all
cases where LValue base info is propagated or constructed in
non-trivial ways. Eventually, we will consider each of these
cases to make sure the TBAA information is correct and not too
conservative. For now, we just fall back to generating TBAA info
from the access type.

This patch should not bring in any functional changes.

This is part of D38126 reworked to be a separate patch to
simplify review.
