At some level of change, it will indeed be safer to stop synchronizing
head and branch, but I believe we're not there yet.

It may be that tree-ssa is commited to HEAD (something I would welcome
for the long term benefit of GCC even if it breaks Ada for a while),
then only the branch will be usable for Ada users.

True, if PRs start to appear on branch and not on HEAD it means
that I've missed the "stop synchronizing" point and need to revert :).
