	(GO_IF_LEGITIMATE_ADDRESS): If assembler supports offsetable
	%lo(), allow it in addresses...
	(PRINT_OPERAND_ADDRESS): ... and print it appropriately.
	* config/sparc/sparc.md (sethi_di_medlow_embmedany_pic): sethi %lo()
	does not make sense.
	* config/sparc/sparc.c (sparc_hard_reg_printed): New array.
	(sparc_output_scratch_registers): New function.
