Hi.

  This patch removes obsolete CLASS_LIKELY_SPILLED_P macro from the AVR back
end in the GCC and introduces equivalent TARGET_CLASS_LIKELY_SPILLED_P target
hook.

  Committed.

        * config/avr/avr.h (CLASS_LIKELY_SPILLED_P): Remove.
        * config/avr/avr-protos.h (class_likely_spilled_p): Remove.
        * config/avr/avr.c (TARGET_CLASS_LIKELY_SPILLED_P): Define.
        (class_likely_spilled_p): Rename to...
        (avr_class_likely_spilled_p): ...this. Make static. Change argument
        type to reg_class_t.



Anatoly.
