[swift-dev] Cleaning up stale branches?

[Alex Blewitt]

There are a lot of branches in the main Swift Git repository at the moment. Many of these appear to be short-term testing branches that are out of date, or work in progress that may be better in an external repository until the work is done. There are also a number of branches (e.g. swift-3.0-preview-*-branch) which are in most cases out-of-step with the tags due to updating version numbers e.g.

9cf1a6f807dd0d36eca20433341a4f1667616431 tag:swift-3.0-PREVIEW-5
b687a0a9d3a4b588ee6c8ca5b43042bbd2fb8586 head:swift-3.0-preview-5-branch

Cleaning up the stale branches will allow others to focus on what the current work areas are, and what are the main branches to be pushing changes to.
