haifa-sched.c (rtx_vec_t): New typedef.
* haifa-sched.c (rtx_vec_t): New typedef.
(contributes_to_priority_p): Extract piece of priority () into new
static function.
(priority): Use the function. Add assertion.
(rank_for_schedule, set_priorities): Add assertion to check that
insn's priority is initialized.
(clear_priorities, calc_priorities): Change signature. Make it update
all relevant insns. Update all callers ('add_to_speculative_block ()'
and 'create_block_check_twin ()').
* sched-int.h (struct haifa_insn_data): Remove field 'priority_known'.
Add new field 'priority_status'.
(INSN_PRIORITY_STATUS): New macro.
(INSN_PRIORITY_KNOWN): Change to use INSN_PRIORITY_STATUS.
