* sbitmap.c (sbitmap_any_common_bits): New function.
* sbitmap.h (sbitmap_any_common_bits): Prototype.
* modulo-sched.c (sms_schedule_by_order): Use sbitmap_any_common_bits
No longer allocate/free "psp", "pss" sbitmaps.
* tree-ssa-alias.c (compute_flow_insensitive_aliasing): Similarly for
the "res" sbitmap.
(group_aliases): Similarly.
