combine: Remove use_crosses_set_p

This removes use_crosses_set_p, and uses modified_between_p instead
everywhere it was used.  This improves optimisation.

* combine.c: Adjust comment.
(use_crosses_set_p): Delete.
(can_combine_p): Use modified_between_p instead of use_crosses_set_p.
(try_combine): Ditto.
