Summary:
Compiling ObjC++ with Clang modules is usually not working well and compiling
the small debugserver with modules is not worth the trouble.

Starting with iOS 13 simulator binaries are identified with an
explicit platform in the new LC_BUILD_VERSION load command.
On older deployment targets using the LC_VERSION_MIN load commands,
this patch detects when an ios process runs on a macOS host and
updates the target triple with the "simulator" environment
accordingly.
(Patch re-applied with bugfix this time).

The debugserver profile thread used to suspend itself between samples with
a usleep. When you detach or kill, MachProcess::Clear would delay replying
to the incoming packet until pthread_join of the profile thread returned.
If you are unlucky or the suspend delay is long, it could take longer than
the packet timeout for pthread_join to return. Then you would get an error
about detach not succeeding from lldb - even though in fact the detach was
successful...
I replaced the usleep with PThreadEvents entity. Then we just call a timed
WaitForEventBits, and when debugserver wants to stop the profile thread, it
can set the event bit, and the sleep will exit immediately.

Seems like this code raised some alarm bells as it looks like an ArrayRef
to a temporary initializer list, but it's actually just calling the ArrayRef(T*, T*)
constructor. Let's clarify this and directly call the right ArrayRef constructor here.

This change will bring lldb-vscode in line with how several other llvm
tools process command line arguments and make it easier to add future
options.

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.
Previous attempts to land this failed on the Windows bot because there's
a dependency between the different process plugins. Apparently
ProcessWindowsCommon needs to be initialized after all other process
plugins but before ProcessGDBRemote.

The WASM and Hexagon plugin check the ArchType rather than the OSType,
so explicitly reject those in the DynamicLoaderStatic.

Generate the LLDB_PLUGIN_DECLARE macros with CMake and a def file. I'm
landing D73067 in pieces so I can bisect what exactly is breaking the
Windows bot.
Other plugins depend on DynamicLoaderDarwinKernel and which means we
cannot conditionally enable/build this plugin based on the target
platform. This means that it will be past of the list of plugins
initialized once that's autogenerated.
Summary:
All of our lookup APIs either use `CompilerDeclContext &` or `CompilerDeclContext *` semi-randomly it seems.
This leads to us constantly converting between those two types (and doing nullptr checks when going from
pointer to reference). It also leads to the confusing situation where we have two possible ways to express
that we don't have a CompilerDeclContex: either a nullptr or an invalid CompilerDeclContext (aka a default
constructed CompilerDeclContext).
This moves all APIs to use references and gets rid of all the nullptr checks and conversions.

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.

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.

After the recent change that grouped some of the ABI plugins together,
those plugins ended up with multiple initializers per plugin. This is
incompatible with my proposed approach of generating the initializers
dynamically, which is why I've grouped them together in a new entry
point.

Summary:
This patch fixes logging to log incoming packets which was removed during a refactor.
We also enable logging to a "vscode.txt" file for each lldb-vscode test by creating the log file in the build artifacts directory for each test. This allows users to see the packets for their tests if needed and the log file is in a directory that will be removed after tests have been run.

This commit fixes an issue with lldb-vscode failing to run programs that
use different architecture/platform than the "empty" in the target.
Original implementation was creating a default target without specifying
the target architecture, platform or program, and then would set
executable file through SBLaunchInfo, assuming that this would update
architecture and platform accordingly. However this wasn't really
happening, and architecture and platform would remain at whatever values
were in the "empty" target. The simple solution is to create target
already for a desired architecture and platform.
Function request_attach is updated in a similar fashion.
This commit also adds new JSON properties to "launch" and "attach"
packets to allow user to override desired platform and architecture.
This might be especially important for cases where information in ELF is
not enough to derive those values correctly.
New code has a behavior similar to LLDB MI [1], where typically IDE would
specify target file with -file-exec-and-symbols, and then only do -exec-run
command that would launch the process. In lldb-vscode those two actions are
merged into one request_launch function. Similarly in the interpreter
session, user would first do "file" command, then "process launch"

Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.

Move the logic for initialization and termination for DynamicLoaderMacOS
into DynamicLoaderMacOSXDYLD so that there's one initializer for the
DynamicLoaderMacOSXDYLD plugin.
Move the logic for initialization and termination for
SymbolFileDWARFDebugMap into SymbolFileDWARF so that there's one
initializer for the SymbolFileDWARF plugin.
StringRef will call strlen on the C string which is inefficient (as ConstString already
knows the string lenght and so does StringRef). This patch replaces all those calls
with GetStringRef() which doesn't recompute the length.
Look up the -arch flags to pass to the mig invocation from an
optionally-defined MIG_ARCHS variable. We can't use CMAKE_OSX_ARCHS
because the {i,tv,watch}OS builds don't use this mechanism to achieve
fat builds (they build each slice separately & then lipo them together).
This supercedes the mig -arch/-isysroot fix from
510758dae2.
Apparently Linux and Windows have the exact opposite behavior when it
comes to inline declarations of external functions. On Linux they're
considered to be part of the lldb_private namespace, while on Windows
they're considered to be part of the top level namespace. Somehow on
macOS, it doesn't really matter and both are fine...
At this point I don't know what to do, so I'm just adding the
LLDB_PLUGIN_DECLARE macros again as originally proposed in D74245.
Summary: This option is not used anymore and has been replaced by the env var LLDBVSCODE_LOG.

Differential revision: https://reviews.llvm.org/D74245
Summary:
There's a fair amount of code duplication between the different ABI plugins for
the same architecture (e.g. ABIMacOSX_arm & ABISysV_arm). Deduplicating this
code is not very easy at the moment because there is no good place where to put
the common code.
Instead of creating more plugins, this patch reduces their number by grouping
similar plugins into a single folder/plugin. This makes it easy to extract
common code to a (e.g.) base class, which can then live in the same folder.
The grouping is done based on the underlying llvm target for that architecture,
because the plugins already require this for their operation.

The developer mode check is now working.
Add another check for user id mismatch, e.g. a regular user
trying to attach to something running as root, and describe
the problem for the user.
This patch has a couple of outstanding issues. The test is not python3
compatible, and it also seems to fail with python2 (at least under some
circumstances) due to an overambitious assertion.
This reverts the patch as well as subsequent fixup attempts:
