  Log Message:
  -----------
  Thread safety analysis: Support builtin pointer-to-member operators

We consider an access to x.*pm as access of the same kind into x, and
an access to px->*pm as access of the same kind into *px. Previously we
missed reads and writes in the .* case, and operations to the pointed-to
data for ->* (we didn't miss accesses to the pointer itself, because
that requires an LValueToRValue cast that we treat independently).

We added support for overloaded operator->* in D124966.

  Thread safety analysis: Don't erase TIL_Opcode type (NFC)

This is mainly for debugging, but it also eliminates some casts.
