[Committed] testsuite: print any leaking torture options for debugging

[Vineet Gupta]

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.
