print-rtl.c (print_rtx): For hard register...

	* print-rtl.c (print_rtx): For hard register, write out register
	number and register name instead of calling PRINT_REG.
	* defaults.h (PRINT_REG): Deleted.
	* config/i386/i386.c (print_reg): Remove handling of CODE of -1.
	Move comments here from i386.h.
	(print_operand, print_operand_address): Call print_reg directly.
	* config/i386/i386.h (PRINT_REG): Deleted.
