	PR 803
	NEWS: Mention "-mtune=[itanium1|itanium2]".

	* config/tc-ia64.c (md): Add tune.
	(md_parse_option): Accepted "-mtune=[itanium1|itanium2]".
	(md_show_usage): Add "-mtune=[itanium1|itanium2]".
	(extra_goodness): Prefer M- and I-unit NOPs for itanium2. F and
	B unit NOPs are discouraged for McKinley-derived cores.
	(md_begin): Don't hardcode the "extra_goodness()" function in
	the comment...
	(ia64_init): Set md.tune to itanium2.

	* doc/as.texinfo: Add -mtune=[itanium1|itanium2]".
	* doc/c-ia64.texi: Likewise.
