Issues with container spec

[kalinon]

Seems aliasing is broken, unsure when it broke, but it should be reproducible with the container spec.

Still get these errors on other llvm versions, so i believe it may have something to do with the changes @HertzDevil may have introduced. @HertzDevil any ideas? Looks like types like std::vector<int> are making through as crystal code. Disabling sanity checks gets output like:

  @[Link(ldflags: "#{__DIR__}/../tmp/containers.o -lstdc++ -lgccpp")]
  lib Binding
    alias Containers = Void
    alias std::vector<int> = Void
