  Since this changes makes the only member of the tdep structure
obsolete, the tdep structure is removed.

gdb/
	* score-tdep.c (score7_linux_gregset): New static regset
	structure.
	(score7_linux_regset_from_core_section): Remove dynamic regset
	allocation.
	(score_gdbarch_init): Drop allocation of tdep structure.
	* score-tdep.h (struct gdbarch_tdep): Remove declaration.
