    * reload.c (struct replacement): Remove SUBREG_LOC member.
    (push_reload): Do not set it.
    (push_replacement): Likewise.
    (subst_reload): Remove dead code.
    (copy_replacements): Remove assertion.
    (copy_replacements_1): Do not handle SUBREG_LOC.
    (move_replacements): Likewise.
    (find_replacement): Remove dead code.  Use reload_adjust_reg_for_mode.
    Detect subregs via recursive descent instead of via SUBREG_LOC.
