    [testsuite] [riscv] xfail ssa-dom-cse-2 on riscv64
    
    For the same reasons that affect alpha and other targets,
    gcc.dg/tree-ssa/ssa-dom-cse-2.c fails to be optimized to the expected
    return statement: the array initializer is vectorized into pairs, and
    DOM cannot see through that.
    
    Add riscv*-*-* to the list of affected lp64 platforms.  riscv32 is
    not affected.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/tree-ssa/ssa-dom-cse-2.c: XFAIL on riscv lp64.
