[lldb/test] Fix data racing issue in TestStackCoreScriptedProcess
This patch should fix an nondeterministic error in TestStackCoreScriptedProcess.
In order to test both the multithreading capability and shared library
loading in Scripted Processes, the test would create multiple threads
that would take the same variable as a reference.
The first thread would alter the value and the second thread would
monitor the value until it gets altered. This assumed a certain ordering
regarding the `std::thread` spawning, however the ordering was not
always guaranteed at runtime.
To fix that, the test now makes use of a `std::condition_variable`
shared between the each thread. On the former, it will notify the other
thread when the variable gets initialized or updated and on the latter,
it will wait until the variable it receives a new notification.
This should fix the data racing issue while preserving the testing
coverage.

This patch includes two related changes:
1. Rewrite `compare` operation to be sound. Current version checks for equality

results are equal. While that works when both are true, it is problematic when
they are both false, because there are four cases in which that's can occur:
both empty, one empty and one unknown (which is two cases), and both unknown. In
the latter three cases, it is unsound to judge them `Same`. This patch changes
`compare` to explicitly check for case of `both empty` and then judge any other
case `Different`.
2. With the change to `compare`, a number of common cases will no longer
terminate. So, we also implement widening to properly handle those cases and
recover termination.

[clang-format][docs] Add ability to link to specific config options
This allows for the creation of permalinks to specific clang-format
options, for better sharing of a specific option and its options.
(I'm adding the usual clang-format reviewers on this patch because
I don't know any other reviewers that well, perhaps someone with
docs experience should be added instead...)
Note that I wanted to make minimal changes to make this happen and thus
landed on an unideal setup, but to me, it seems like the best out of
worse ones.
I could have made every style option a subheading, which would add
automatically the logic for permalinks and the little paragraph icon for
sharing.
However, this meant that the links themselves would be suboptimal, as
they'd include the whole text of the heading, including the type and
versionbadge, which is needless noise and could change, breaking the
concept of a "permalink". The format of the page could be changed to
put the option names on their own in a heading, and the other info below
it in a paragraph.
As Sphinx seems unwilling to fix https://github.com/sphinx-doc/sphinx/issues/1961,
there isn't a succinct way to change the "id" html field used for
sections
I could have used an add-on (https://github.com/GeeTransit/sphinx-better-subsection),
or made one myself, but I wanted to avoid extra dependencies for no
reason. (plus, I don't know how to make one myself.)
I could have used raw HTML for each heading, but that would immensely
pollute the rst file, which, while it is generated, is currently still
human-readable and it'd be nice for it to stay that way.
Also note that sphinx treats references as case-insensitive, which means
that they will all be lowercased in the resulting HTML. I envisioned
the ability to simply add #OptionName after the URL to get placed right
at the desired config option, which isn't possible without things such
as inline `raw` HTML.
To reconcile that, I added the ¶ paragraph buttons that can be used to
generate the link to the desired section, but since headings are not
actually used, they are faked and literally just a link following each
option, which means they stylistically don't match all other headings.
Also note that this sort-of assumes HTML output. I know Sphinx can
output other formats but I do not know if they are used. A non-html
output could embed unusable ¶ signs everywhere.
I'm okay with this patch being rejected in its current solution, or if
any of the above listed alternatives are better, they could be pursued
instead. In case the downsides of this solution are too much, I will
just create a feature request issue for this and maybe let someone more
experienced with Sphinx handle it, since this is still a feature I would
like to have. (and I do not want to deal with Sphinx at all after
battling with it for a whole day to produce a mediocre result.)

[clang] Reland parenthesized aggregate init patches
This commit relands the patches for implementing P0960R3 and P1975R0,
which describe initializing aggregates via a parenthesized list.
The relanded commits are:
*
40c52159d3ee - P0960R3 and P1975R0: Allow initializing aggregates from
a parenthesized list of values
*
c77a91bb7ba7 - Remove overly restrictive aggregate paren init logic
*
32d7aae04fdb - Fix a clang crash on invalid code in C++20 mode
This patch also fixes a crash in the original implementation.
Previously, if the input tried to call an implicitly deleted copy or
move constructor of a union, we would then try to initialize the union
by initializing it's first element with a reference to a union. This
behavior is incorrect (we should fail to initialize) and if the type of
the first element has a constructor with a single template typename
parameter, then Clang will explode. This patch fixes that issue by
checking that constructor overload resolution did not result in a
deleted function before attempting parenthesized aggregate
initialization.
Additionally, this patch also includes D140159, which contains some
minor fixes made in response to code review comments in the original
implementation that were made after that patch was submitted.
