    * 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.
