  Changed paths:
    M clang/lib/CodeGen/CodeGenTBAA.cpp
    A clang/test/CodeGenCXX/may_alias.cpp

  Log Message:
  -----------
  Fix detection of __attribute__((may_alias)) to properly look through
type sugar.

We previously missed the attribute in a lot of cases in C++, because
there's often other type sugar there (eg, ElaboratedType).
