Suggest Rust 2018 on `<expr>.await` with no such field
When type checking a field projection (`fn check_field`) to `<expr>.await` where `<expr>: τ` and `τ` is not a primitive type, suggest switching to Rust 2018. E.g.
```
error[E0609]: no field `await` on type `std::pin::Pin<&mut dyn std::future::Future<Output = ()>>`
--> $DIR/suggest-switching-edition-on-await.rs:31:7
|
LL | x.await;
| ^^^^^ unknown field
|
= note: to `.await` a `Future`, switch to Rust 2018
= help: set `edition = "2018"` in `Cargo.toml`
= note: for more on editions, read https://doc.rust-lang.org/edition-guide
```
Fixes https://github.com/rust-lang/rust/issues/63533
This PR also performs some preparatory cleanups in `fn check_field`; the last 2 commits are where the suggestion is introduced and tested respectively.

Continue refactoring resolve and hygiene
The general goal is addressing FIXMEs from the previous PRs.
Merging similar data structures (+ prerequisites for such merging), accounting for the fact that all `ExpnId`s have associated data in `HygieneData` now (less `Option`s).
Also, some renaming.
This should be the last renaming session in this area, I think.

Currently, librustc_llvm builds are not reproducible because the LLVM
files it compiles use the debug version of llvm_unreachable, which
uses __FILE__. To fix this, we propagate NDEBUG from bootstrap if
applicable and use it when compiling librustc_llvm.
The previous approach was brittle - what would happen if `ParentScope` wasn't created by `invoc_parent_scope`?
That's exactly the case for various uses of `ParentScope` in diagnostics and in built-in attribute validation.
Traces already contain module info without that.
It's easy to forget to call `finalize_*` on a module.
In particular, macros enum and trait modules weren't finalized.
By happy accident macros weren't placed into those modules until now.
on OpenBSD, some architectures relies on libc++ (from LLVM) and some
others on libestdc++ (particular version of libstdc++ from GCC).
sparc64-unknown-openbsd needs libestdc++ and libgcc (as x86_64 some
years ago). Reintroduce the support of them for openbsd, only for
sparc64 arch. Some others architectures on OpenBSD could use them too.
cleanup: Remove `Spanned` where possible
It generally only makes sense on enums, otherwise it's more convenient to "flatten" it by adding a span field to the struct it wraps.
