// - Each variant points to the file and line of its yield point
Remove artificial flag from generator variants - Literally, variants are not artificial. We have `yield` statements, upvars and inner variables in the source code. - Functionally, we don't want debuggers to suppress the variants. It contains the state of the generator, which is useful when debugging. So they shouldn't be marked artificial. - Debuggers may use artificial flags to find the active variant. In this case, marking variants artificial will make debuggers not work properly. Fixes #79009.

//
Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed.

debuginfo: Refactor debuginfo generation for types 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
