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.
