If you feel strongly about it I can do it as a pre-commit change, but personally I don't think it's worth the churn.


================
Comment at: lldb/source/Commands/CommandObjectTarget.cpp:1404
   std::lock_guard<std::recursive_mutex> guard(module_list.GetMutex());
   const size_t num_modules = module_list.GetSize();
   if (num_modules > 0) {

There's a few places in this file where that's true, but here we still need it for both the early return and the print statement. I'm being pedantic, but generally `::size` is only guaranteed to be `O(n)` as opposed to `::empty` which is `O(1)`. I think having the temporary variable here is fine. 


================
Comment at: lldb/source/Plugins/DynamicLoader/MacOSX-DYLD/DynamicLoaderMacOS.cpp:406
+  Target &target = m_process->GetTarget();
+  const size_t num_modules = target.GetImages().GetSize();

It is below, but I've inlined it.
