    testsuite: print any leaking torture options for debugging
    
    This was helpful when debugging the recent multilib testsuite failure.
    
    gcc/testsuite:
            * lib/torture-options.exp: print the value of non-empty options:
            torture_without_loops, torture_with_loops, LTO_TORTURE_OPTIONS.
