[NDS32] Provide TARGET_CMODEL_[SMALL|MEDIUM|LARGE] to check which code model is specified. 

gcc/
	* config/nds32/nds32.h (TARGET_CMODEL_SMALL): New macro.
	(TARGET_CMODEL_MEDIUM): New macro.
	(TARGET_CMODEL_LARGE): New macro.
	* config/nds32/nds32.c (nds32_asm_file_start): Display corresponding
	code model setting in assembly code.
