Merge branch 'al/bisect-first-parent'
"git bisect" learns the "--first-parent" option to find the first
breakage along the first-parent chain.
* al/bisect-first-parent:
bisect: combine args passed to find_bisection()
bisect: introduce first-parent flag
cmd_bisect__helper: defer parsing no-checkout flag
rev-list: allow bisect and first-parent flags
t6030: modernize "git bisect run" tests
