[SCORE] Hookize PREFERRED_RELOAD_CLASS

[SCORE] Hookize PREFERRED_RELOAD_CLASS

[Anatoly Sokolov]

   Hi.

   This patch removes obsolete PREFERRED_RELOAD_CLASS macro from the SCORE 
back end in the GCC and introduces equivalent TARGET_PREFERRED_RELOAD_CLASS 
target hook.

   Untested.

   OK to install?

	* config/score/score.h (PREFERRED_RELOAD_CLASS): Remove.
	* config/score/score-protos.h (score_preferred_reload_class): Remove.
	* config/score/score.c (TARGET_PREFERRED_RELOAD_CLASS: Define.
	(score_preferred_reload_class): Make static. Change return and
	'rclass' argument type to reg_class_t.
