PR rtl-optimization/45352
* sel-sched.c (find_best_expr): Do not set pneed_stall when
the variable_issue hook is not implemented.
(fill_insns): Remove dead variable stall_iterations.
(init_seqno_1): Force EBB start for resetting sched cycles on any
successor blocks of the rescheduled region.
(sel_sched_region_1): Use bitmap_bit_p instead of bitmap_clear_bit.
(reset_sched_cycles_in_current_ebb): Add debug printing.
New variable issued_insns.  Advance state when we have issued
issue_rate insns.
