Add new sparc options to control instruction availability.
gas/
* config/tc-sparc.c (hwcap_allowed): New.
(struct sparc_arch): New field 'hwcap_allowed' containing a bitmask
of F_FOO flags which are enabled by the particular arch setting.
Add new options that provide explicit access to new instructions.
(md_parse_option): Only bump max_architecture if the requested one
is larger, or this is the first explicit request.
(get_hwcap_name): New function.
(sparc_ip): Validate that hwcaps used by an instruction have actually
been enabled.
* doc/c-sparc.texi: Document new sparc options.
