There are not that many patches that need to go to the branch, so in
the past I have just used svn directly. I is fairly simple for this:

$ svn co https://llvm.org/svn/llvm-project/llvm/branches/release_33
$ build a patch with git, in the same way you would for sending it for
review (the branch is missing on the git mirror, but I expect it to
show up soon).
$ cd /the/path/release_33
$ patch -p1 < your_patch.patch
$ svn commit
