+        else
+          CGF.EmitLValue(ME->getBase());
+        return *Constant;
There's an EmitIgnoredExpr you could use.

Also, I think it would be fine to add a generic tryEmitMemberExprAsConstant that takes a MemberExpr and does this DRE stuff behind the scenes; it's not at all different for the different emitters.
