Split out async fn and generator test This keeps FileCheck from tripping over unimportant differences in codegen.

// Verify debuginfo for async fn:
// - 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: Make sure that type names for closure and generator environments are unique in debuginfo. Before this change, closure/generator environments coming from different instantiations of the same generic function were all assigned the same name even though they were distinct types with potentially different data layout. Now we append the generic arguments of the originating function to the type name. This commit also emits '{closure_env#0}' as the name of these types in order to disambiguate them from the accompanying closure function '{closure#0}'. Previously both were assigned the same name.

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
