Douglas Gregor e41d7feaf5 Optimize ModuleManager::visit() by precomputing the visitation order ...

and limiting ourselves to two memory allocations. 10% speedup in
-fsyntax-only time for modules.

With this change, we can actually see some performance different from
the global module index, but it's still about 1%.
