    RISC-V Regression tests: Fix FAIL of pr97832* for RVV
    
    These cases are vectorized by vec_load_lanes with strided = 8 instead of SLP
    with -fno-vect-cost-model.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/pr97832-2.c: Adapt dump check for target supports load_lanes with stride = 8.
            * gcc.dg/vect/pr97832-3.c: Ditto.
            * gcc.dg/vect/pr97832-4.c: Ditto.
