The code in Named_type::do_get_backend in the Go frontend was not
passing the correct flag value for circular function types to
Backend::circular_pointer_type (it was always setting this flag to
false). This patch by Than McIntosh passes a true value if the type
being converted is a function type.  Bootstrapped and ran Go testsuite
on x86_64-pc-linux-gnu.  Committed to mainline.
