* infcmd.c: Include "reggroups.h" and <ctype.h>.
	(print_float_info): Print registers in float_reggroup.
	(print_vector_info): Print registers in vector_reggroup.
	(default_print_registers_info): When all, print registers in
	all_reggroup.  Otherwize, print registers in general_reggroup.
	(registers_info): Rewrite.  Add support for register groups.
	Eliminate a goto.
