Hi.

  This patch removes obsolete CLASS_LIKELY_SPILLED_P macro from the M32C back
end in the GCC and introduces equivalent TARGET_CLASS_LIKELY_SPILLED_P target
hook.

  Regression tested on m32c-unknown-elf.

  OK to install?

        * config/m32c/m32c.h (CLASS_LIKELY_SPILLED_P): Remove.
        * config/m32c/m32c-protos.h (m32c_class_likely_spilled_p): Remove.
        * config/m32c/m32c.c (TARGET_CLASS_LIKELY_SPILLED_P): Define.
        (m32c_class_likely_spilled_p): Make static. Change arguments type to
        reg_class_t.



Anatoly.
