[Reproducer] Move GDB Remote Provider into Reproducer (NFC)
95a6db9 
Originally the idea was for providers to be defined close to where they
are used. While this helped designing the providers in such a way that
they don't depend on each other, it also means that it's not possible to
access them from a central place. This proved to be a problem for some
providers and resulted in them living in the reproducer class.

The ProcessGDBRemote provider is the last remaining exception. This
patch makes things consistent and moves it into the reproducer like the
other providers.

[Reproducer] Move the command loader into the reproducer (NFC)
c428757 
This just moves the CommandLoader utility into the reproducer namespace
and makes it accessible outside the API layer. This is setting things up
for a bigger change.

@JDevlieghere
[Reproducer] Always use absolute paths for capture & replay.
f50e5b1 
The VFS requires files to be have absolute paths. The file collector
makes paths relative to the reproducer root. If the root is a relative
path, this would trigger an assert in the VFS. This patch ensures that
we always make the given path absolute.

Thank you Ted Woodward for pointing this out!

[Reproducer] Capture the debugger's working directory
258416b 
This patch extends the reproducer to capture the debugger's current
working directory. This information will be used later to set the
current working directory of the VFS.

[Reproducer] Add reproducer dump command.
a0b3c0c 
This adds a reproducer dump commands which makes it possible to inspect
a reproducer from inside LLDB. Currently it supports the Files, Commands
and Version providers. I'm planning to add support for the GDB Remote
provider in a follow-up patch.

[Reproducer] Move GDB Remote Packet into Utility. (NFC)
423f3ba 
To support dumping the reproducer's GDB remote packets, we need the
(de)serialization logic to live in Utility rather than the GDB remote
plugin. This patch renames StreamGDBRemote to GDBRemote and moves the
relevant packet code there.

Its uses in the GDBRemoteCommunicationHistory and the
GDBRemoteCommunicationReplayServer are updated as well.

[NFC] Move dumping into GDBRemotePacket

This moves the dumping logic from the GDBRemoteCommunicationHistory

reproducer command object.

[lldb][TypeSystem] ForEach: Don't hold the TypeSystemMap lock across …
ac6d5b1 
…callback

The `TypeSystemMap::m_mutex` guards against concurrent modifications
of members of `TypeSystemMap`. In particular, `m_map`.

`TypeSystemMap::ForEach` iterates through the entire `m_map` calling
a user-specified callback for each entry. This is all done while
`m_mutex` is locked. However, there's nothing that guarantees that
the callback itself won't call back into `TypeSystemMap` APIs on the
same thread. This lead to double-locking `m_mutex`, which is undefined
behaviour. We've seen this cause a deadlock in the swift plugin with
following backtrace:

```

int main() {
    std::unique_ptr<int> up = std::make_unique<int>(5);

    volatile int val = *up;
    return val;
}

clang++ -std=c++2a -g -O1 main.cpp

./bin/lldb -o “br se -p return” -o run -o “v *up” -o “expr *up” -b
```
