  Log Message:
  -----------
  LICM: Drop -licm-force-thread-model-single in favor of the module flag

Now that the threading model is carried by the "thread-model" IR module flag,
the hidden -licm-force-thread-model-single override is redundant: a test can
select the single-threaded model by setting the module flag directly.
isThreadLocalObject reads only Module::getThreadModel.
