When there's a type mismatch we make an effort to check if it was
caused by a function's return type. This logic now makes sure to
only point at the return type if the error happens in a tail
expression.
Where possible, the error message includes the name of the crate
that brought in the crate with duplicate lang items (which
helps with debugging). This information is passed on from cstore
using the `extern_crate` query.
Rename `*.node` to `*.kind`, and `hair::Pattern*` to `hair::Pat*`
In both `ast::Expr` and `hir::Expr`:
- Rename `Expr.node` to `Expr.kind`.
- Rename `Pat.node` to `Pat.kind`.
- Rename `ImplItem.node` to `ImplItem.kind`.
- Rename `Lit.node` to `Lit.kind`.
- Rename `TraitItem.node` to `TraitItem.kind`.
- Rename `Ty.node` to `Ty.kind`.
- Rename `Stmt.node` to `Stmt.kind`.
- Rename `Item.node` to `Item.kind`.
- Rename `ForeignItem.node` to `ForeignItem.kind`.
- Rename `MetaItem.node` to `MetaItem.kind`.
Also:
- Rename `hair::FieldPattern` to `hair::FieldPat`.
- Rename `hair::PatternKind` to `hair::PatKind`.
- Rename `hair::PatternRange` to `hair::PatRange`.
- Rename `PatternContext` to `PatCtxt`.
- Rename `PatternTypeProjection` to `PatTyProj`.
- Rename `hair::Pattern` to `hair::Pat`.
These two sets of changes are grouped together to aid with merging. The only changes are renamings.

When the panic handler is run, the existing Handler may be in a weird
state if it was responsible for triggering the panic. By using a freshly
created Handler, we avoid trying to re-entrantly lock a HandlerInner,
which was causing a double panic on ICEs.
Fix ExitStatus on Fuchsia
Fuchsia exit codes don't follow the convention of libc::WEXITSTATUS et
al, and they are 64 bits instead of 32 bits. This gives Fuchsia its own
representation of ExitStatus.
Additionally, the zircon syscall structs were out of date, causing us to
see bogus exit codes.

Fix issue #64732
Based on issue #64732, when creating a byte literal with single quotes,
the suggestion message would indicate that you meant to write a `str` literal,
but we actually meant to write a byte string literal.
So I changed the unescape_error_reporting.rs to decide whether to print out
"if you meant to write a `str` literal, use double quotes",
or "if you meant to write a byte string literal, use double quotes".
Fixes#64732.
Remove tx_to_llvm_workers from TyCtxt
This can be kept within the codegen backend crates entirely -- there's no reason for us to create it outside and attempt to hold it in the (global) context.
Changes here aren't really too easily reviewable I suspect -- not sure if they can be cleaned up by splitting into more commits though, it's just hard to reason about `Box<Any>` in general. If there are thoughts though I'd be happy to hear them.
The primary goal of this PR is to get rid of the field on `rustc_interface::Queries`.
Rename `subst::Kind` to `subst::GenericArg`
And `subst::UnpackedKind` to `subst::GenericArgKind`. Individual variable names (e.g. `kind`) are not renamed, which would be an infeasible mission.
Fixes https://github.com/rust-lang/rust/issues/64352.
