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.
