Cleanup some surrounding code.
Support resolution of intra doc links in unnamed block scopes.
(Paths from rustdoc now use early resolution and no longer need results of late resolution like all the built ribs.)
Fix one test hitting file path limits on Windows.
Move methods logically belonging to build-reduced-graph into `impl BuildReducedGraphVisitor` and `build_reduced_graph.rs`
Move types mostly specific to late resolution closer to the late resolution visitor
Move `Resolver` fields specific to late resolution to the new visitor.
The `current_module` field from `Resolver` is replaced with two `current_module`s in `LateResolutionVisitor` and `BuildReducedGraphVisitor`.
Outside of those visitors `current_module` is replaced by passing `parent_scope` to more functions and using the parent module from it.
Visibility resolution no longer have access to later resolution methods and has to use early resolution, so its diagnostics in case of errors regress slightly.
Sort the fat LTO modules to produce deterministic output.
Some projects that use LTO for their release builds are not reproducible. We can fix this by sorting the fat LTO modules before using them.
It might also be useful to do this for thin LTO, but I couldn't get that to work to test it so I didn't do it.

Fix#61933.
Tweak mismatched types error
- Change expected/found for type mismatches in `break`
- Be more accurate when talking about diverging match arms
- Tweak wording of function without a return value
- Suggest calling bare functions when their return value can be coerced to the expected type
- Give more parsing errors when encountering `foo(_, _, _)`
Fix#51767, fix#62677, fix#63136, cc #37384, cc #35241, cc #51669.
Give built-in macros stable addresses in the standard library
Continuation of https://github.com/rust-lang/rust/pull/62086.
Derive macros corresponding to traits from libcore are now available through the same paths as those traits:
- `Clone` - `{core,std}::clone::Clone`
- `PartialEq` - `{core,std}::cmp::PartialEq`
- `Eq` - `{core,std}::cmp::Eq`
- `PartialOrd` - `{core,std}::cmp::PartialOrd`
- `Ord` - `{core,std}::cmp::Ord`
- `Default` - `{core,std}::default::Default`
- `Debug` - `{core,std}::fmt::Debug`
- `Hash` - `{core,std}:#️⃣:Hash`
- `Copy` - `{core,std}::marker::Copy`
Fn-like built-in macros are now available through libcore and libstd's root module, by analogy with non-builtin macros defined by libcore and libstd:
```rust
{core,std}::{
__rust_unstable_column,
asm,
assert,
cfg,
column,
compile_error,
concat,
concat_idents,
env,
file,
format_args,
format_args_nl,
global_asm,
include,
include_bytes,
include_str,
line,
log_syntax,
module_path,
option_env,
stringify,
trace_macros,
}
```
Derive macros without a corresponding trait in libcore or libstd are still available only through prelude (also see https://github.com/rust-lang/rust/pull/62507).
Attribute macros also keep being available only through prelude, mostly because they don't have an existing practice to follow. An advice from the library team on their eventual placement would be appreciated.
```rust
RustcDecodable,
RustcEncodable,
bench,
global_allocator,
test,
test_case,
```
r? @alexcrichton
Hard-float (unlike mips32 musl targets but consistent with any other
musl target), MIPS64r2, n64 ABI.
The triples are renamed to carry the `abi64` ABI suffix found on all
other MIPS64 targets, for consistency and forward compatibility, should
Rust gain support for the n32 ABI one day.
