C-SKY: Delete LO_REGS and HI_REGS, use HILO_REGS instead.
gcc/ChangeLog:
* config/csky/constraints.md ("l", "h"): Delete.
* config/csky/csky.h (reg_class, REG_CLASS_NAMES,
REG_CLASS_CONTENTS): Delete LO_REGS and HI_REGS.
* config/csky/csky.c (regno_reg_classm,
csky_secondary_reload, csky_register_move_cost):
Use HILO_REGS instead of LO_REGS and HI_REGS.
