bisect: add support for bisecting bare repositories
This enhances the support for bisecting history in bare repositories.
The "git bisect" command no longer needs to be run inside a repository
with a working tree; it defaults to --no-checkout when run in a bare
repository.
Two tests are included to demonstrate this behaviour.

This option may be useful when the test you would perform in each step
does not require a checked out tree.
++
+If the repository is bare, `--no-checkout` is assumed.
