re PR debug/53740 (--enable-checking=yes,rtl bootstrap failure with ada)

PR debug/53740
* df.h (dead_debug_add): Remove third argument.
* df-problems.c (dead_debug_add): Likewise. Use the REGNO of the
REG that we want to replace instead.
(dead_debug_insert_temp): Use the REGNO of the reg that we want
to replace instead of DF_REF_REGNO. Require there to always be
at least one such use. Check for cases where the same location
has more than df_ref associated with it.
(df_note_bb_compute): Remove third dead_debug_add argument.
* dce.c (word_dce_process_block): Likewise.
