I'm working on a lower-level intrusive list that can be used stand-alone, and splitting the files up a bit will make the code easier to organize. Explode the ilist headers in advance to improve blame lists in the future. - Move ilist_node_base from ilist_node.h to ilist_node_base.h. - Move ilist_base from ilist.h to ilist_base.h. - Move ilist_iterator from ilist.h to ilist_iterator.h. - Move ilist_node_access from ilist.h to ilist_node.h to support ilist_iterator. - Update unit tests to #include smaller headers. - Clang-format the moved things. I noticed in transit that there is a simplify_type specialization for ilist_iterator. Since there is no longer an implicit conversion from ilist<T>::iterator to T*, this doesn't make sense (effectively it's a form of implicit conversion). For now I've added a FIXME. llvm-svn: 280047
