Hi, all,

This patch is to prepare more constraints in nds32 implementation.
They will be used in the future patch.

Committed as Rev.254800: http://gcc.gnu.org/r254800

gcc/
	* config/nds32/constraints.md: Provide more constraints.
	* config/nds32/nds32.h (enum reg_class, REG_CLASS_NAMES,
	REG_CLASS_CONTENTS): Define R5_REG, R8_REG, and FRAME_POINTER_REG to
	support constraints usage.


Best regards,
jasonwucj
