8d1c5700f0 Rollup merge of #40369 - petrochenkov:segspan, r=eddyb
Give spans to individual path segments in AST

And use these spans in path resolution diagnostics.

The spans are spans of identifiers in segments, not whole segments. I'm not sure what spans are more useful in general, but identifier spans are a better fit for resolve errors.

HIR still doesn't have spans.

syntax: add `ast::ItemKind::MacroDef`, simplify hygiene info

This PR
 - adds a new variant `MacroDef` to `ast::ItemKind` for `macro_rules!` and eventually `macro` items,
 - [breaking-change] forbids macro defs without a name (`macro_rules! { () => {} }` compiles today),
 - removes `ast::MacroDef`, and
 - no longer uses `Mark` and `Invocation` to identify and characterize macro definitions.
   - We used to apply (at least) two `Mark`s to an expanded identifier's `SyntaxContext` -- the definition mark(s) and the expansion mark(s). We now only apply the latter.

rustc: Whitelist the FMA target feature

This commit adds the entry `"fma\0"` to the whitelist for the x86
target. LLVM already supports fma but rustc did not directly. Previously
rustc permitted `+fma` in the target-feature argument and enabled the use
of FMA instructions, but it did not list it in the configuration and
attributes.

Disallow subtyping between T and U in T: Unsize<U>.

Because `&mut T` can be coerced to `&mut U`, `T` and `U` must be unified invariantly. Fixes #40288.
E.g. coercing `&mut [&'a X; N]` to `&mut [&'b X]` must require `'a` be equal to `'b`, otherwise you can convert between `&'a X` and `&'b X` (in either direction), potentially unsoundly lengthening lifetimes.

Subtyping here was introduced with `Unsize` in #24619 (landed in 1.1, original PR is #23785).

4b1dfbd86c Auto merge of #40308 - nikomatsakis:incr-comp-isolate-task, r=mw
first pass at isolating dep-graph tasks

This intentionally leaves `DepGraph::in_task()`, the more common form,
alone. Eventually all uses of `DepGraph::in_task()` should be ported
to `with_task()`, but I wanted to start with a smaller subset.

I also used `AssertDepGraphSafe` on the closures that are found in
trans. This is because the types there are non-trivial and I wanted to
lay down the mechanism and come back to the more subtle cases.

The current approach taken in this PR has a downside: it is necessary
to manually "reify" fn types into fn pointers when starting a task,
like so:

    dep_graph.with_task(..., task_fn as fn(_))

this is because `with_task` takes some type `T` that implements
`DepGraphTask` rather than taking a `fn()` type directly. *This* is so
that we can accept closure and also so that we can accept fns with
multiple arities. I am not sure this is the right approach.

Originally I wanted to use closures bound by an auto trait, but that
approach has some limitations:

- the trait cannot have a `read()` method; since the current method
  is unused, that may not be a problem.
- more importantly, we would want the auto trait to be "undefined" for all types
  *by default* -- that is, this use case doesn't really fit the typical
  auto trait scenario. For example, imagine that there is a `u32` loaded
  out of a `hir::Node` -- we don't really want to be passing that
  `u32` into the task!

rustbuild: Build documentation for `proc_macro`

This commit fixes #38749 by building documentation for the `proc_macro` crate by
default for configured hosts. Unfortunately did not turn out to be a trivial
fix. Currently rustbuild generates documentation into multiple locations: one
for std, one for test, and one for rustc. The initial fix for this issue simply
actually executed `cargo doc -p proc_macro` which was otherwise completely
elided before.

Unfortunately rustbuild was the left to merge two documentation trees together.
One for the standard library and one for the rustc tree (which only had docs for
the `proc_macro` crate). Rustdoc itself knows how to merge documentation files
(specifically around search indexes, etc) but rustbuild was unaware of this, so
an initial fix ended up destroying the sidebar and the search bar from the
libstd docs.

To solve this issue the method of documentation has been tweaked slightly in
rustbuild. The build system will not use symlinks (or directory junctions on
Windows) to generate all documentation into the same location initially. This'll
rely on rustdoc's logic to weave together all the output and ensure that it ends
up all consistent.

Closes #38749

[MIR] Implement Inlining

Fairly basic implementation of inlining for MIR. Uses conservative

Doesn't handle a number of cases, but can be extended later. This is basically the same as the previous inlining PR, but without the span-related changes (as the bugs it was dealing with have since been fixed).

rustc: Support auto-retry linking on a segfault

This is a last-ditch attempt to help our pain with dealing with #38878 on the
bots. A new environment variable is added to the compiler,
`RUSTC_RETRY_LINKER_ON_SEGFAULT`, which will instruct the compiler to
automatically retry the final linker invocation if it looks like the linker
segfaulted (up to 2 extra times).

Unfortunately there have been no successful attempts to debug #38878. The only
information seems to be that the linker (e.g. `ld` on OSX) is segfaulting
somewhere in some thread pool implementation. This appears to be spurious as
failed PRs will later merge.

The hope is that this helps the queue keep moving without clogging and delaying
PRs due to #38878.
