Richi has asked the we break the wide-int patch so that the individual port and
front end maintainers can review their parts without have to go through the
entire patch. This patch covers the scheduler code.
Ok?
* sched-vis.c
(print_value): Handle CONST_WIDE_INT.
* sel-sched-ir.c
(lhs_and_rhs_separable_p): Update comment.
