Summary:
When importing the main FileID the ASTImporter currently gives it no include location. This means
that any SourceLocations produced for this FileID look to Clang as if they are coming from the
main FileID (as the main FileID has no include location).
Clang seems to expect that there is only one main FileID in one translation unit (which makes sense
during normal compilation), so this behavior leads to several problems when producing diagnostics,
one being that when calling `SourceManager::isBeforeInTranslationUnit` on two SourceLocations
that come from two different ASTContext instances, Clang fails to sort the SourceLocations as
the include chains of the FileIDs don't end up in a single FileID. This causes that Clang crashes
with "Unsortable locations found" in this function.
This patch gives any imported main FileIDs the main FileID of the To ASTContext as its include
location. This allows Clang to sort all imported SourceLocations as now all include chains point
to the main FileID of the To ASTContext. The exact include location is currently set to the start
of the To main file (just because that should always be a valid SourceLocation).

LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch
unifies the header guards across LLDB and converts everything to match
LLVM's style.

This helps this transform occur earlier so we can fold the not
with setcc. If we delay it until after type legalization we might
have introduced instructions to widen the mask if the vselect was
widened. This can prevent the not from making it to the setcc.
We could of course add more DAG combines to handle that, but
moving this earlier is easier.
This is useful for performing custom build system integration that works by appending '--analyze --analyzer-output html' to all clang build commands.
For such users there is now still a way to have the fancy index.html file
in the output.

In the path-sensitive vfork() checker that keeps a list of operations
allowed after a successful vfork(), unforget to include execve() in the list.
Patch by Jan Včelák!
Differential Revision: https://reviews.llvm.org/D73629
Summary:
Depends on https://reviews.llvm.org/D71899.
The third in a series of patches that ports the LLVM coroutines passes
to the new pass manager infrastructure. This patch implements 'coro-elide'.
The new pass manager infrastructure does not implicitly repeat CGSCC
pass pipelines when a function is devirtualized, and so the tests
for the new pass manager that rely on that behavior now explicitly
specify `repeat<2>`.

Summary:
This patch has four dependencies:
1. The first in this series of patches that implement coroutine passes in the
new pass manager: https://reviews.llvm.org/D71898.
2. A patch that introduces an API for CGSCC passes to add new reference
edges to a `LazyCallGraph`, `updateCGAndAnalysisManagerForCGSCCPass`:
https://reviews.llvm.org/D72025.
3. A patch that introduces a `CallGraphUpdater` helper class that is
capable of mutating internal `LazyCallGraph` state in order to insert
new function nodes into a specific SCC: https://reviews.llvm.org/D70927.
4. And finally, a small edge case fix for updating `LazyCallGraph` that
patch 3 above happens to run into: https://reviews.llvm.org/D72226.
This is the second in a series of patches that ports the LLVM coroutines
passes to the new pass manager infrastructure. This patch implements
'coro-split'.
Some notes:
* Using the new CGSCC pass manager resulted in IR being printed in the
reverse order in some tests. To prevent FileCheck checks from failing due
to these reversed orders, this patch splits up test files that test
multiple different coroutine functions: specifically
coro-alloc-with-param.ll, coro-split-eh.ll, and coro-eh-aware-edge-split.ll.
* CoroSplit.cpp contained 2 overloads of `splitCoroutine`, one of which
dispatched to the other based on the coroutine ABI being used (C++20
switch-based versus Swift returned-continuation-based). I found this
confusing, especially with the additional branching based on `CallGraph`
vs. `LazyCallGraph`, so I removed the ABI-checking overload of
`splitCoroutine`.

Use LLDB_PLUGIN_DEFINE_ADV to make the name of the generated initializer
match the name of the plugin. This is a step towards generating the
initializers with a def file. I'm landing this change in pieces so I can
narrow down what exactly breaks the Windows bot.
This patch changes the way we initialize and terminate the plugins in
the system initializer. It uses an approach similar to LLVM's
TARGETS_TO_BUILD with a def file that enumerates the plugins.
The previously landed patch got reverted because it was lacking:
(1) A plugin definition for the Objective-C language runtime,
(2) The dependency between the Static and WASM dynamic loader,
(3) Explicit initialization of ScriptInterpreterNone for lldb-test.
All issues have been addressed in this patch.

For a file in WebKit, this brings the time spent in LiveDebugValues down
from 16 minutes to 2 minutes. The reduction comes from iterating the set
of open variable locations just once in transferRegisterDef. Post-patch,
the most expensive item inside of transferRegisterDef is a call to
VarLoc::isDescribedByReg, which we have to do.
Testing: I built LNT using the Os-g cmake cache with & without this
patch, then diffed the object files to verify there was no binary diff.

We have one title in every doc which corresponds to `#`, in the some
there are multiple and it is expected to be h1 headers (visual elements
rather than organizational). Indent every nesting by one in all of the
docs with multiple titles.
Also fixing trailing whitespace.
I readily admit that I don't know why this fixes the modules build, but
it seems to get things building again. Previously I saw the error
