    MIPS/testsuite: add -mno-branch-likely to r10k-cache-barrier-13.c
    
    In mips.cc(mips_reorg_process_insns), there is this claim:
    
        Also delete cache barriers if the last instruction
        was an annulled branch.  INSN will not be speculatively
        executed.
    
    And with -O1 on mips64, we can generate binary code like this,
    which fails this test.
    
    gcc/testsuite
            * gcc.target/mips/r10k-cache-barrier-13.c: Add -mno-branch-likely
            option.
