* config/sparc/tm-sp64.h (REGISTER_RAW_SIZE): Lower 32 fp regs

	have size 4.
	(REGISTER_VIRTUAL_SIZE): Likewise.
	(REGISTER_VIRTUAL_TYPE): Lower 32 fp regs have type float.
	Upper 32 fp regs have type double.
	* sparc-tdep.c (NUM_SPARC_FPREGS): Replace with
	(FP_REGISTER_BYTES): this, and update all uses.
	(FP_MAX_REGNUM): Define if not already.
	(get_saved_register): Handle new sparc64 fp regs.
	(sparc_frame_find_saved_regs): Likewise.
	(sparc_print_register_hook): Only print fp regs < 32 as doubles.
	Add code to handle long doubles when gdb does.
	(_initialize_sparc_tdep): Use print_insn_sparc64 if sparc64.
