The test was being skipped on the Windwos bot because it requires Python
which was silently disabled because of a configuration issue. Now that
the test runs, this fails as expected.

multiple GDB remotes"
On multiple retry this issue won't duplicate - will revisit with author if
duplication works again.
This reverts commit c9e0b354e2749ce7ab553974692cb35c8651a869.

remotes
This was causing a crash in opt+assert builds on linux and a follow-up
message was posted.

When running the test suite with always capture on, a handful of tests
are failing because they have multiple targets and therefore multiple
GDB remote connections. The current reproducer infrastructure is capable
of dealing with that.
This patch reworks the GDB remote provider to support multiple GDB
remote connections, similar to how the reproducers support shadowing
multiple command interpreter inputs. The provider now keeps a list of
packet recorders which deal with a single GDB remote connection. During
replay we rely on the order of creation to match the number of packets
to the GDB remote connection.

Make it possible to override reproducer capture with the
LLDB_CAPTURE_REPRODUCER environment variable.
The goal of this change is twofold.
(1) I want to be able to enable capturing reproducers during regular
test runs, both locally and on the bots. To do so I need a way to
force capture. I cannot do this through the Python API, because
reproducer capture must be enabled *before* the debugger
initialized, which happens automatically when doing `import lldb`.
(2) I want to provide an escape hatch for when reproducers are enabled
by default. Downstream we have reproducer capture enabled by default
in the driver.
This patch solves both problems by overriding the reproducer mode based
on the environment variable. Acceptable values are 0/1 and ON/OFF.

To ensure a reproducer works correctly, the version of LLDB used for
capture and replay must match. Right now the reproducer already contains
the LLDB version. However, this is purely informative. LLDB will happily
replay a reproducer generated with a different version of LLDB, which
can cause subtle differences.
This patch adds a version check which compares the current LLDB version
with the one in the reproducer. If the version doesn't match, LLDB will
refuse to replay. It also adds an escape hatch to make it possible to
still replay the reproducer without having to mess with the recorded
version. This might prove useful when you know two versions of LLDB
match, even though the version string doesn't. This behavior is
triggered by passing a new flag -reproducer-skip-version-check to the
lldb driver.

This patch hooks the reproducer infrastructure with the signal handlers.
When lldb crashes with reproducers capture enabled, it will now generate
the reproducer and print a short message the standard out. This doesn't
affect the pretty stack traces, which are still printed before.
This patch also introduces a new reproducer sub-command that
intentionally raises a given signal to test the reproducer signal
handling.
Currently the signal handler is doing too much work. Instead of copying
over files into the reproducers in the signal handler, we should
re-invoke ourselves with a special command line flag that looks at the
VFS mapping and performs the copy.
This is a NO-OP when reproducers are disabled.

For some reason the reproducer tests seem really proficient at
uncovering structural issues in LLDB related to how we tear down things,
but of course only on the bots.
The pretty stack trace helps a bit, but what I really want is the crash
reports which contain much more information, such as what other threads
we doing.
Crash reports are automatically suppressed by lit. This patch
(temporarily) disables that for the reproducer tests.

If lldb was run in capture mode, but no reproducer was generated, make
sure we clean up the reproducer directory.

Summary:
This patch addresses an ambiguity in how our existing tests invoke the
compiler. Roughly two thirds of our current "shell" tests invoke the
compiler to build the executables for the host. However, there is also
a significant number of tests which don't build a host binary (because
they don't need to run it) and instead they hardcode a certain target.
We also have code which adds a bunch of default arguments to the %clang
substitutions. However, most of these arguments only really make sense
for the host compilation. So far, this has worked mostly ok, because the
arguments we were adding were not conflicting with the target-hardcoding
tests (though they did provoke an occasional "argument unused" warning).
However, this started to break down when we wanted to use
target-hardcoding clang-cl tests (D69031) because clang-cl has a
substantially different command line, and it was getting very confused
by some of the arguments we were adding on non-windows hosts.
This patch avoid this problem by creating separate %clang(xx,_cl)_host
substutitions, which are specifically meant to be used for compiling
host binaries. All funny host-specific options are moved there. To
ensure that the regular %clang substitutions are not used for compiling
host binaries (skipping the extra arguments) I employ a little
hac^H^H^Htrick -- I add an invalid --target argument to the %clang
substitution, which means that one has to use an explicit --target in
order for the compilation to succeed.

I'm having a hard time reproducing this and it's failing on the Windows
bot. Temporarily X-failing this test while I continue to try building
LLDB on Windows.

Now that the VFS knows how to deal with virtual working directories, we
can set the current working directory to the one we recorded during
reproducer capture. This ensures that relative paths are resolved
correctly during replay.

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.

LLDB has three major testing strategies: unit tests, tests that exercise
the SB API though dotest.py and what we currently call lit tests. The
later is rather confusing as we're now using lit as the driver for all
three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM
repository layout.
