Builds and webrevs

[Aleksey Shipilev]

Hi,

Is there interest in having regular CI builds for panama/dev? If so, what branches are interesting
to build? It would be nice to have some common branch like amber/amber has in "amber-demo", but
individual branches are fine too. See for example:
  https://builds.shipilev.net/openjdk-amber/

Also, in Shenandoah project, we eventually figured that having the automatically-generated webrevs
against upstream is a very convenient tool for debugging (figuring what exactly was changed), review
(sometimes, accidental changes leak in, and cause head-scratchy bugs), and merges (because you can
tell if the change is coming from your code). It also makes newcomers happy with high-level overview
that was changed.

This is the example for amber/amber, amber-demo branch (among other patches for other projects):
  https://builds.shipilev.net/patch-openjdk-amber-amber-demo/

If you tell me which Panama branches are interesting to webrev, I can add them to the mix. What CI
builds and what it webrevs does not have to be the same branches.

Cheers,
