* reorg.c (try_merge_delay_insns): Account for resources referenced
in each instruction in INSN's delay list before trying to eliminate
useless instructions. Similarly when looking at a trial insn's delay
slots.
* reorg.c (check_annul_list_true_false): New function.
(steal_delay_list_from_{target,fallthrough}): Call it and also
refine tests for when we may annul if already filled a slot.
(fill_slots_from_thread): Likewise.
(delete_from_delay_slot): Return newly-created thread.
(try_merge_delay_isns): Use its new return value.
