premature optimizer says that this would avoid constructing a
second/temporary string if it was:
std::string foo = getParentContextString(...);
foo += Name.str();
or
std::string Fullname = getParentContextString(Context) + Name.str();
(at least the latter will work in C++11, invoking the move ctor)
But that's by no means necessary if you prefer the legibility of your
original form.

Would it be better to implement these 3 lines with a call to
addGlobalName(Ty.getName(), Entry->getEntry(), Context); ?

Probably no optimization problem here, but std::string CS; would be just as
good.

And !Name.empty(), perhaps? But again, reasonable people may disagree with
me there.
