tcwg-llvm-release.sh: Use tags instead of branches

We are currently pulling the release script from
branches/release_${MAJOR}${MINOR}

This is a problem for the 7.1.0 release (first minor version with the
new, post-LLVM-4.0 numbering scheme) because the release_71 branch
doesn't exist. We could ask for it to be created, but it seems more
robust to pull from tags/RELEASE_${MAJOR}${MINOR}${PATCH}/${RC} instead,
since that's the path used by the upstream test-release.sh itself.

Note that this doesn't work for --candidate values of 'trunk' or
'branch=', but I'm not sure the current version works either (in any
case I didn't manage to guess a parameter combination that would work
with such values). That can be fixed in a future patch.
