commit 196e8948d0eebcdcb62d2d746d4eba8e813fa233

    RISC-V Regression test: Fix FAIL of fast-math-slp-38.c for RVV
    
    Reference: https://godbolt.org/z/G9jzf5Grh
    
    RVV is able to vectorize this case using SLP. However, with -fno-vect-cost-model,
    RVV vectorize it by vec_load_lanes with stride 6.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/fast-math-slp-38.c: Add ! vect_strided6.
    
    (cherry picked from commit 784deda0da6062edc0ace62fd7cf1abbcf2fb054)
