[NDS32] Define and rename some GPR-specific stuff.
* config/nds32/nds32.c (nds32_function_arg): Define and rename some
GPR-specific stuff.
(nds32_function_arg_advance): Likewise.
(nds32_init_cumulative_args): Likewise.
* config/nds32/nds32.h (NDS32_MAX_GPR_REGS_FOR_ARGS): Define.
(NDS32_FIRST_GPR_REGNUM): Define.
(NDS32_LAST_GPR_REGNUM): Define.
(NDS32_AVAILABLE_REGNUM_FOR_GPR_ARG): Define.
(NDS32_ARG_PASS_IN_REG_P): Use NDS32_MAX_GPR_REGS_FOR_ARGS.
(FUNCTION_ARG_REGNO_P): Use NDS32_MAX_GPR_REGS_FOR_ARGS.
(machine_function): Use GRP-specific stuff.
