Thanks for the review!

It's not very clear to me what exactly this means. But I think we are still
not taking how member was accessed into account. The access in `DeclAccessPair`
describes how a member was accessed, and this should be None instead of the
access specifier of the member as we don't have this information here.
I updated the wording in the comment to make this a bit clearer.
================
Comment at: lib/Sema/SemaCodeComplete.cpp:1316-1317
+ // void D::f() { this->^; }
+ // The completion after "this->" will have `InBaseClass` set to true
and
+ // `Ctx` set to "B". We need to set the actual accessing context (i.e.
+ // naming class) to "D" so that access can be calculated correctly.

It's a bit messy, but this is roughly how lookup inside a class, say D,works:
1. lookup inside the class (InBaseClass = false, Context=D).
2. Run the same lookup on all base classes (InBaseClass=true, Context=B).
(https://github.com/llvm-mirror/clang/blob/master/lib/Sema/SemaLookup.cpp#L3584)
So, `InBaseClass` would be true when a lookup starts from a derived class.
