This bumps the requirement to enable Graphite to using cloog 0.17.0
which is the last release from upstream. The patch removes the
support for the legacy cloog versions, too.
I am bootstrapping and testing this now with cloog 0.17.0 built
against the upstream ISL 0.10 version.
If this ends up being approved I will put the cloog 0.17.0 tarball
in the infrastructure directory.
Bootstrap and regtest pending on x86_64-unknown-linux-gnu.
Ok for trunk (for the build parts)?
Thanks,
Richard.
