rebase: refactor can_fast_forward into goto tower

Before, can_fast_forward was written with an if-else statement. However,
in the future, we may be adding more termination cases which would lead
to deeply nested if statements.

Refactor to use a goto tower so that future cases can be easily
inserted.
