This moves all cctest files for the compiler to live in the same namespace as the components they are testing. Hence we can avoid the forbidden using directives pulling in entire namespaces. From the Google C++ style guide: "You may not use a using-directive to make all names from a namespace available". This would be covered by presubmit linter checks if build/namespaces were not blacklisted.
