All fields except the discriminant (including `outer_fields`)
should be put into structures inside the variant part, which gives
an equivalent layout but offers us much better integration with
debuggers.

 - 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 rust-lang#79009.

This should fix linking of other C code (and soon Rust-generated code)
on aarch64 musl.

Make AssertKind::fmt_assert_args public

Fix debuginfo for generators

First, all fields except the discriminant (including `outer_fields`) should be put into structures inside the variant part, which gives an equivalent layout but offers us much better integration with debuggers.

Second, artificial flags in generator variants should be removed.
 - Literally, variants are not artificial. We have `yield` statements, upvars and inner variables in the source code.
