Support the configure setting --with-arch =la664, and support

gcc/ChangeLog:

        * config.gcc: Support LA664.
        * config/loongarch/genopts/loongarch-strings: Likewise.
        * config/loongarch/genopts/loongarch.opt.in: Likewise.
        * config/loongarch/loongarch-cpu.cc (fill_native_cpu_config): Likewise.
        * config/loongarch/loongarch-def.c: Likewise.

There should be

Ok, I will revise it as soon as possible.

Thanks.
