        PR target/21623:

        * regclass.c (FORBIDDEN_INC_DEC_CLASSES): Remove

        (memory_move_secondary_cost, init_reg_autoinc): Remove
        SECONDARY_INPUT_RELOAD_CLASS / SECONDARY_OUTPUT_RELOAD_CLASS tests.
        Replace SECONDARY_{IN,OUT}PUT_RELOAD_CLASS use with
        secondary_reload_class call.
        (copy_cost): Likewise.  Add new parameter prev_sri.  Changed all
        callers.
        * reload.c (entire file): Remove HAVE_SECONDARY_RELOADS checks.
        (push_secondary_reload): Use secondary_reload target hook.

        SECONDARY_OUTPUT_RELOAD_CLASS tests.  Replace
        SECONDARY_{IN,OUT}PUT_RELOAD_CLASS use with secondary_reload_class
call.
        * reload.h (HAVE_SECONDARY_RELOADS): Don't define nor test.
        (secondary_reload_class, scratch_reload_class): Declare.

        are for intermediate registers.
        (emit_output_reload_insns): Replace SECONDARY_OUTPUT_RELOAD_CLASS use
        with secondary_reload_class call.  Support case when both secondary
        & tertiary reloads are for intermediate registers.
        * target-def.h (TARGET_SECONDARY_RELOAD): Provide default definition.
        (TARGET_INITIALIZER) Add TARGET_SECONDARY_RELOAD.
        * target.h (secondary_reload_info): New struct / typedef.
