In the Go frontend, for the main package, we add an implicit import of the runtime package, to ensure that it is initialized. That import used the predeclared location, which caused various tests, notably Named_type::is_builtin, to treat these imported names as builtin. Start using a real location, so that those tests do the right thing. Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. Committed to mainline.
