tm.texi (Label Output): Document ASM_OUTPUT_LABEL_REF.

Browse Source 
* doc/tm.texi (Label Output): Document ASM_OUTPUT_LABEL_REF.
	* final.c (output_addr_const): Use ASM_OUTPUT_LABEL_REF.
	* config/stormy16/stormy16.c (xstormy16_print_operand): For '%C',
	don't print an @fptr for labels either.
	(xstormy16_output_addr_vec): Don't print @fptr here.
	* config/stormy16/stormy16.h (ASM_OUTPUT_LABEL_REF): New macro.
