Loongarch64 architecture defines 128 bit vector extension lsx and 256 bit vector extension lasx. The cpucfg instruction can be used to obtain whether the CPU has a corresponding extension. This part of code is added to prepare for the subsequent addition of corresponding vector instruction optimization.
