    RISC-V Regression test: Fix FAIL of pr45752.c for RVV
    
    RVV use load_lanes with stride = 5 vectorize this case with -fno-vect-cost-model
    instead of SLP.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/pr45752.c: Adapt dump check for target supports load_lanes with stride = 5.
