GCC versions < 12 do not support __builtin_shufflevector, though they do support an alternative builtin named __builtin_shuffle. It requires that the indices are passed as an integer vector as opposed to variadic arguments. This enables us to benefit from potentially improved and better performing code generation for intrinsics that are implemented with this builtin.
