i386: Call get_available_features for all CPUs with max_level >= 1 [PR100758]

get_available_features doesn't depend on cpu_model2->__cpu_{family,model}
and just sets stuff up based on CPUID leaf 1, or some extended ones,
so I wonder why are we calling it separately for Intel, AMD and Zhaoxin
and not for all other CPUs too?  I think various programs in the wild
which aren't using __builtin_cpu_{is,supports} just check the various CPUID
leafs and query bits in there, without blacklisting unknown CPU vendors,
so I think even __builtin_cpu_supports ("sse2") etc. should be reliable
if those VENDOR_{CENTAUR,CYRIX,NSC,OTHER} CPUs set those bits in CPUID leaf
1 or some extended ones.  Calling it for all CPUs also means it can be
inlined because there will be just a single caller.

I have tested it on Intel and Martin tested it on AMD, but can't test it
on non-Intel/AMD; for Intel/AMD/Zhaoxin it should be really no change in
behavior.

	PR target/100758
	* common/config/i386/cpuinfo.h (cpu_indicator_init): Call
	get_available_features for all CPUs with max_level >= 1, rather
	than just Intel or AMD.
