How about this style as an alternative?:

immutable bool mmx;
immutable bool hasPopcnt;

shared static this()

     import gcc.builtins;
     mmx       = __builtin_cpu_supports("mmx"   ) > 0;
     hasPopcnt = __builtin_cpu_supports("popcnt") > 0;
}

Please do not invent an alternative interface, use the one in core.cpuid:
