Description
During each new edition, it is a bit of a hassle to add/remove -Zunstable-options headers for the next edition. I think it would be helpful to automatically specify -Zunstable-options when an edition header specifies an unstable edition. This means there would roughly be one place to make the switch (compiletest itself).

Research direction
Start in compiletest's handling of edition headers and inspect how it currently processes -Zunstable-options. The work is done when unstable editions automatically receive that option, eliminating the need to add or remove separate headers for each new edition; verify the compiletest behavior around edition-based tests.
