All branches and tags, including deleted ones, were converted (under 
not-fetched-by-default refs in some cases); the git repository has 
everything that might plausibly be useful, omitting only a few things that 
would have been meaningless to convert, such as mistaken branch creations 
in the root of the repository and the SVN hooks directory.  Use "git 
ls-remote git://gcc.gnu.org/git/gcc.git" to see the full list of over 5000 
refs available in the repository (or do a clone with --mirror to fetch 
them all).

That branch is refs/vendors/google/heads/gcc-4_8 (refs/vendors/ isn't 
fetched by default, but it's there).  (The old SVN repository is also 
still available at svn://gcc.gnu.org/svn/gcc .)
