Kevin Daudt f88851c637 rev-list: refuse --first-parent combined with --bisect
rev-list --bisect is used by git bisect, but never together with
--first-parent. Because rev-list --bisect together with --first-parent
is not handled currently, and even leads to segfaults, refuse to use
both options together.

Because this is not supported, it makes little sense to use git log
--bisect --first parent either, because refs/heads/bad is not limited to
the first parent chain.
