    RISC-V: Suppress bogus warning for VLS types
    
    This patch fixes over 100+ bogus FAILs due to experimental vector ABI warning.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv.cc (riscv_pass_in_vector_p): Only allow RVV type.
    
    (cherry picked from commit a0e042d61dadc6bdcbeaa3b712b7a83415a12547)
