This used to be done to avoid inlining impls referencing private items,
but is now unnecessary since we actually check that impls do not
reference non-doc-reachable items.
rustdoc: Only record the same impl once
Due to inlining it is possible to visit the same module multiple times during `<Cache as DocFolder>::fold_crate`, so we keep track of the modules we've already visited.

Remove IPV6_V6ONLY functionality
These settings can only be adjusted before bind time, which doesn't make
sense in the current set of functionality. These methods are stable, but
haven't hit a stable release yet.

Will also need a backport to the beta.
rustbuild: Run all markdown documentation tests
This commit adds support to rustbuild to run all documentation tests, basically
running `rustdoc --test` over all our documentation.
Sanity check Python on OSX for LLDB tests
Two primary changes:
* Don't get past the configure stage if `python` isn't coming from `/usr/bin`
* Call `debugger.Terminate()` to prevent segfaults on newer versions of LLDB.

port compiletest to use JSON output
This uncovered a lot of bugs in compiletest and also some shortcomings
of our existing JSON output. We had to add information to the JSON
output, such as suggested text and macro backtraces. We also had to fix
various bugs in the existing tests.
Joint work with @jonathandturner.

Implement `append` for b-trees.
I have finally found time to revive #26227, this time only with an `append` implementation.
The algorithm implemented here is linear in the size of the two b-trees. It firsts creates
a `MergeIter` from the two b-trees and then builds a new b-tree by pushing
key-value pairs from the `MergeIter` into nodes at the right heights.
Three functions for stealing have been added to the implementation of `Handle` as
well as a getter for the height of a `NodeRef`.
The docs have been updated with performance information about `BTreeMap::append` and
the remark about B has been removed now that it is the same for all instances of `BTreeMap`.

configure: Support --disable-option-checking
I'm trying to package Rust for Fedora (this is nothing official (yet)).
The standard RPM packaging process involves running `./configure` with a whole lot of options that are commonly recognized by autotools configure scripts, but not by Rust's one. Since it does not make much sense to support all of this options, I think it would be great to support at least `--disable-option-checking`, so Rust's configure script would not fail.
[The old attempt](https://github.com/fabiand/rust-spec/blob/master/rustc.spec) to package Rust used a sed script (at line 72), but this is not the recommended way to do that.
The example uses integers for the value being iterated over, but the indices
added by `enumerate` are also integers, so I always end up double taking and
thinking harder than I should when parsing the documentation. I also always
forget which order the index and value are in the tuple so I frequently hit this
stumbling block. This commit changes the documentation to iterate over
characters so that it is immediately obvious which part of the tuple is the
index and which is the value.

This pass was supposed to check use of gated features before
`#[cfg]`-stripping but this was not the case since it in fact happens
after. Checks that are actually important and must be done before macro
expansion are now made where the features are actually used. Close#32648.
Also ensure that attributes on macro-generated macro invocations are
checked as well. Close#32782 and #32655.
Split core::iter module implementation into parts

split iter.rs into a directory of (implementation private) modules.

+ range (range related)

rustdoc: Fix the strip-hidden `ImplStripper`
Instead of stripping impls which reference *stripped* items, we keep impls which reference *retained* items. We do this because when we strip an item we immediately return, and do not recurse into it - leaving the contained items non-stripped from the point of view of the `ImplStripper`.

MIR: Do not require END_BLOCK to always exist
Basically, all this does, is removing restriction for END_BLOCK to exist past the first invocation of RemoveDeadBlocks pass. This way for functions whose CFG does not reach the `END_BLOCK` end up not containing the block.
As far as the implementation goes, I’m not entirely satisfied with the `BasicBlock::end_block`. I had hoped to make `new` a `const fn` and then just have a `const END_BLOCK` private to mir::build, but it turns out that constant functions don’t yet support conditionals nor a way to assert.
rustbuild: Package librustc & co for cross-hosts
Currently the `rust-std` package produced by rustbuild only contains the
standard library plus libtest, but the makefiles actually produce a `rust-std`
package with all known target libraries (including libsyntax, librustc, etc).
Tweak the behavior so the dependencies of the `dist-docs` step in rustbuild
depend on the compiler libraries as well (so that they're all packaged).
Closes#32984
