bisect--helper: introduce new decide_next() function

Let's refactor code from bisect_next_check() into a new
decide_next() helper function.

This removes some goto statements and makes the code simpler,
clearer and easier to understand.

While at it `bad_ref` and `good_glob` are not const any more
to void casting them inside `free()`.
