8258772: Some runtime/cds tests fail with +LogCompilation or +StressX
Emit warning about TraceDependencies results in ClassHierarchyWalker::count_find_witness_calls() only if TraceDependencies is actually enabled. Use standard warning() function instead of ad hoc printing. Remove warning about using Stress(LCM|GCM|IGVN) without LogCompilation in Compile::Compile(), and add the information to the description of the StressSeed option instead. These changes prevent false test failures when using LogCompilation or Stress(LCM|GCM|IGVN). Reviewed-by: chagedorn, kvn, thartmann
