Jonas Devlieghere 9494c510af [lldb] Use C++11 default member initializers
This converts a default constructor's member initializers into C++11
default member initializers. This patch was automatically generated with
clang-tidy and the modernize-use-default-member-init check.

$ run-clang-tidy.py -header-filter='lldb' -checks='-*,modernize-use-default-member-init' -fix

This is a mass-refactoring patch and this commit will be added to
.git-blame-ignore-revs.

Jonas Devlieghere bb894b9782 [lldb] Extract reproducer providers & co into their own header.
Extract all the provider related logic from Reproducer.h and move it
into its own header ReproducerProvider.h. These classes are seeing most
of the development these days and this reorganization reduces
incremental compilation from ~520 to ~110 files when making changes to
the new header.

Jonas Devlieghere bad61548b2 [Reproducers] Serialize process arguments in ProcessInfo
While debugging why TestProcessList.py failed during passive replay, I
remembered that we don't serialize the arguments for ProcessInfo. This
is necessary to make the test pass and to make platform process list -v
behave the same during capture and replay.

Jonas Devlieghere 2451cbf07b [lldb/Reproducers] Intercept the FindProcesses API
This patch extends the reproducers to intercept calls to FindProcesses.
During capture it serializes the ProcessInstanceInfoList returned by the
API. During replay, it returns the serialized data instead of querying
the host.

The motivation for this patch is supporting the process attach workflow
during replay. Without this change it would incorrectly look for the
inferior on the host during replay and failing if no matching process
was found.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Raphael Isemann 808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Walter Erquinigo 48a50ee034 [android/process list] support showing process arguments
Summary:
The qfProcessInfo and qsProcessInfo packets currently don't set the processes' arguments, however the platform process list -v command tries to print it.
In this diff I'm adding the arguments as part of the packet, and now the command shows the arguments just like on mac.

On Mac:

Pavel Labath a8b18baa0f ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested, take 2
Summary:
The previous attempt at making nameless process not match when searching for a
given name failed because the macos implementation was depending on this detail
in its partial matching strategy. Doing partial matching to avoid expensive
lookups is a perfectly valid thing to do, the way it was implemented seems
somewhat unexpected.

This patch implements it differently by providing special
methods in the ProcessInstanceInfoMatch which match only a subset of fields,
and changes mac host code to use those instead.

Then, it re-applies r373925 to get make the ProcessInstanceInfoMatch with a
name *not* match a nameless process.

Pavel Labath f7bd5bffed ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested
Since D68289, a couple of tests on linux started being extremely flaky.
All of them were doing name-based attaching and were failing because
they couldn't find an unambiguous process to attach to.

The patch above changed the process finding logic, so that failure to
find a process name does not constitute an error. This meant that a lot
more transient processes showed up in the process list during the test
suite run. Previously, these processes would not appear as they would be
gone by the time we went to read their executable name, arguments, etc.

Now, this alone should not cause an issue were it not for the fact that
we were considering a process with no name as if it matched by default
(even if we were explicitly searching for a process with a specified
name). This meant that any of the "transient" processes with no name
would make the name match ambiguous. That clearly seems like a bug to me
so I fix that.

Walter Erquinigo e0a398bf31 [process list] make the TRIPLE column wider
Summary:
Now that `process list` works better on the android platform, the arch aarch64-unknown-linux-android appears quite often.
The existing printed width of the TRIPLE column is not long enough, which doesn't look okay.
E.g.
```
1561   1016                    aarch64-unknown-linux-android ip6tables-restore
1999   1                       aarch64-unknown-linux-android tlc_server
2332   982                                              com.android.systemui
2378   983                                              webview_zygote
```

Now, after adding 6 spaces, it looks better

```
PID    PARENT USER       TRIPLE                         NAME
====== ====== ========== ============================== ============================
...
1561   1016              aarch64-unknown-linux-android  ip6tables-restore
1999   1                 aarch64-unknown-linux-android  tlc_server
2332   982                                              com.android.systemui

Zachary Turner 805e71060e Move ProcessInfo from Host to Utility.
There are set of classes in Target that describe the parameters of a
process - e.g. it's PID, name, user id, and similar. However, since it
is a bare description of a process and contains no actual functionality,
there's nothing specifically that makes this appropriate for being in
Target -- it could just as well be describing a process on the host, or
some hypothetical virtual process that doesn't even exist.

To cement this, I'm moving these classes to Utility. It's possible that
we can find a better place for it in the future, but as it is neither
Host specific nor Target specific, Utility seems like the most appropriate
place for the time being.

After this there is only 2 remaining references to Target from Host,
which I'll address in a followup.
