	disambiguate flag names starting with "no".
	(cpu_arch): Add negated bit definitions.  Add
	".nop" CPU extension.
	(i386_align_code): Use new .cpunop bit to decide
	when to generate alignment using nops.
	(set_cpu_arch): Use negated bit instead to decide
	when to use cpu_flags or vs. cpu_flags_and_not.
	(md_parse_option): Likewise.
