There's a lot of stuff wrong with the representation of these types:
TyFnDef doesn't actually uniquely identify a function, TyFnPtr is used to
represent method calls, TyFnDef in the sub-expression of a cast isn't
correctly reified, and probably some other stuff I haven't discovered yet.
Splitting them seems like the right first step, though.
Make errors for unnecessary visibility qualifiers consistent
This PR refactors away `syntax::parse::parser::ParsePub` so that unnecessary visibility qualifiers on variant fields are reported not by the parser but by `privacy::SanePrivacyVisitor` (thanks to @petrochenkov's drive-by improvements in #31919).

tests: add test for empty <>
Rust allows to specify an empty list of type and lifetime parameters, but there are no tests for it:
```
user@UNIT-326 [12:53:45] [~/projects/rust] [diamonds-and-rust]
-> % grep "<>" -R src/test
src/test/compile-fail/generic-type-params-name-repr.rs: // And don't print <> at all when there's just defaults.
src/test/debuginfo/issue22656.rs:// when trying to handle a Vec<> or anything else that contains zero-sized
```
So let's add them! Besides it's such a wonderful opportunity to put a reference to Judas Priest band into the branch name ;)
For example if `Command::output` or `Command::status` is used then stdin is just
immediately closed. Add an option for this so as an optimization we can avoid
creating pipes entirely.
This should help reduce the number of active file descriptors when spawning
processes on Unix and the number of active handles on Windows.
This pushes the implementation detail of proxying `read_to_end` through to
`read_to_end_uninitialized` all the way down to the `FileDesc` and `Handle`
implementations on Unix/Windows. This way intermediate layers will also be able
to take advantage of this optimized implementation.
This commit also adds the optimized implementation for `ChildStdout` and
`ChildStderr`.
This defines `_mm256_broadcast_ps` and `_mm256_broadcast_pd`. The `_ss`
and `_sd` variants are not supported by LLVM. In Clang these intrinsics
are implemented as inline functions in C++.
Intel reference: https://software.intel.com/en-us/node/514144.
Note: the argument type should really be "0hPc" (a pointer to a vector
of half the width), but internally the LLVM intrinsic takes a pointer to
a signed integer, and for any other type LLVM will complain. This means
that a transmute is required to call these intrinsics.
The AVX2 broadcast intrinsics `_mm256_broadcastss_ps` and
`_mm256_broadcastsd_pd` are not available as LLVM intrinsics. In Clang
they are implemented using the shufflevector builtin.

Right now whenever rustdoc inlines a struct or enum from another crate it ends
up inlining *all* `impl` items found in the other crate at the same time. The
rationale for this was to discover all trait impls which are otherwise not
probed for. This unfortunately picks up a lot of impls of public traits for
private types, causing lots of broken links.
This commit instead hoards all of those inlined impls into a temporary storage
location which is then selectively drawn from whenever we inline a new type.
This should ensure that we still inline all relevant impls while avoiding all
private ones.
This is actually a reexported implementation detail in the `rt::v1` module but
rustdoc doesn't like reexporting items from `doc(hidden)` modules. Do what we'd
end up doing anyway from an API perspective and make a public-facing `enum` that
can be retranslated under the hood if necessary.
A few categories:
* Links into compiler docs were just all removed as we're not generating
compiler docs.
* Move up one more level to forcibly go to std docs to fix inlined documentation
across the facade crates.
Add a script to get run which verifies that `href` links in documents are
correct. We're always getting a steady stream of "fix a broken link" PRs and
issue reports, and we should probably just nip them all in the bud.
