re PR debug/43161 (Wrong debug info in guality/vla-1.c (f2))
PR debug/43161
* regcprop.c (struct queued_debug_insn_change): New type.
(struct value_data_entry): Add debug_insn_changes field.
(struct value_data): Add n_debug_insn_changes field.
(debug_insn_changes_pool): New variable.
(free_debug_insn_changes, apply_debug_insn_changes,
cprop_find_used_regs_1, cprop_find_used_regs): New functions.
(kill_value_one_regno): Call free_debug_insn_changes if needed.
(init_value_data): Clear debug_insn_changes and n_debug_insn_changes
fields.
(replace_oldest_value_reg): Don't change DEBUG_INSNs, instead queue
changes for them.
(copyprop_hardreg_forward_1): Don't call apply_change_group for
DEBUG_INSNs. For a real insn, if there are queued DEBUG_INSN
changes, call cprop_find_used_regs via note_stores.
(copyprop_hardreg_forward): When copying vd from predecessor
which has any queued DEBUG_INSN changes, make sure the pointers are
cleared. At the end call df_analyze and then if there are any
DEBUG_INSN changes queued at the end of some basic block for still
live registers, apply them.
(pass_cprop_hardreg): Set TODO_df_finish in todo_flags_finish.
