8258772: Some runtime/cds tests fail with +LogCompilation or +StressX

Browse source 
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).
