OK.
Unfortunately the patch as-is seems at least incomplete, thus to be sure
I reverted it for now and re-opened the PR: trying to actually use the
type showed issues in the gimplifier, see below. If you have hints about
that I would be glad to further look into the issue (but, honestly, this
isn't a regression, I don't think it can be considered an high priority
issue now)
Thanks,
Paolo.
