Well. This testcase would have been "self contained" (in that GCC
itself is the testcase) and it *is* a clear regression, but given the
current trend, what can we realistically do about it?
(I find it a bit disturbing that several old PRs of mine which
describe clear performance regressions are getting closed these
days without any form of resolution, but let's assume there are
other, better(?) PRs for this problem in our database.)
