    LoongArch: testsuite:Added additional vectorization "-mlasx" compilation option.
    
    In the LoongArch architecture, the reason for not adding the 128-bit
    vector-width-*hi* instruction template in the GCC back end is that it causes
    program performance loss, so we can only add the "-mlasx" compilation option
    to use 256-bit vectorization functions in test files.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/bb-slp-pattern-1.c: If you are testing on the
            LoongArch architecture, you need to add the "-mlasx" compilation
            option to generate vectorized code.
            * gcc.dg/vect/slp-widen-mult-half.c: Dito.
            * gcc.dg/vect/vect-widen-mult-const-s16.c: Dito.
            * gcc.dg/vect/vect-widen-mult-const-u16.c: Dito.

            * gcc.dg/vect/vect-widen-mult-u16.c: Dito.
            * gcc.dg/vect/vect-widen-mult-u8-s16-s32.c: Dito.
