H.J. Lu 2210942396 Don't generate multi-byte NOPs for i686. 
gas/

2010-08-06  Quentin Neill <quentin.neill@amd.com>

	* config/tc-i386.c (arch_entry): Add negated bit to
	  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.
