I suppose we could have a baseline about clang bootstrap + lit tests
(what test-release.sh does essentially) passes on major platforms.

But the really interesting question for me is really what kind of bugs
we're considering as release blocking. It's the trade-off between
shipping on (or not too much behind schedule) and delaying to
investigate more issues that's tricky..

The latest release made it clear we don't track compile time very
well, or at least not well enough to catch the regressions in that
release early enough.

Also I think there's no 32-bit Windows buildbot anymore :/
