This commit - changes names to use di_node instead of metadata - uniformly names all functions that build new debuginfo nodes build_xyz_di_node - renames CrateDebugContext to CodegenUnitDebugContext (which is more accurate) - moves TypeMap and functions that work directly work with it to a new type_map module - moves and reimplements enum related builder functions to a new enums module - splits enum debuginfo building for the native and cpp-like cases, since they are mostly separate - uses SmallVec instead of Vec in many places - removes the old infrastructure for dealing with recursion cycles (create_and_register_recursive_type_forward_declaration(), RecursiveTypeDescription, set_members_of_composite_type(), MemberDescription, MemberDescriptionFactory, prepare_xyz_metadata(), etc) - adds type_map::build_type_with_children() as a replacement for dealing with recursion cycles - adds many (doc-)comments explaining what's going on - changes cpp-like naming for C-Style enums so they don't get a enum$<...> name (because the NatVis visualizer does not apply to them) - fixes detection of what is a C-style enum because some enums where classified as C-style even though they have fields - changes the position of discriminant debuginfo node so it is consistently nested inside the top-level union instead of, sometimes, next to it
