[webkit-dev] The Purpose of Core Builders

The Core Builders are a failed experiment (for which I am guilty).
They were intended as a set of builders which when green would allow
the CommitQueue to commit.  This was long before the CommitQueue knew
how to commit when the bots were red (like real humans do).

I know of no set of builders @ build.webkit.org which are consistently
green (Core or otherwise), so the distinction is of little meaning
anymore. :)

I would vote we just remove the concept of Core Builders at this point.
