The original patch got reverted because it broke `check-lldb` on a clean
build. This fixes that.

as it appears to have broken check-lldb.
This reverts r374184 (git commit 22314179f0660c172514b397060fd8f34b586e82)

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.

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.

Now that the LLDB instrumentation macros are in place, we should use
that to test reproducer replay.

The test had an implicit constructor for the Foo struct. Also, as the
instrumentation doesn't have to be reproducer specific, I moved the
tests into the lit/tools directory.

In r353906 we hooked up clang and lldb's reproducer infrastructure to
capture files used by clang. This patch adds the necessary logic to have
clang reuse the files from lldb's reproducer during replay.

This patch hooks up clang and lldb's reproducers functionality. It
ensures that when capturing a reproducer, headers and modules imported
through the expression parser are collected.

This patch introduces a new tool called 'lldb-instr'. It automates the
workflow of inserting LLDB_RECORD and LLDB_REGSITER macros for
instrumentation.
Because the tool won't be part of the build process, I didn't want to
over-complicate it. SB_RECORD macros are inserted in place, while
SB_REGISTER macros are printed to stdout, and have to be manually copied
into the Registry's constructor. Additionally, the utility makes no
attempt to properly format the inserted macros. Please use clang-format
to format the changes after running the tool.

This patch adds the file provider which is responsible for capturing
files used by LLDB.
When capturing a reproducer, we use a file collector that is very
similar to the one used in clang. For every file that we touch, we add
an entry with a mapping from its virtual to its real path. When we
decide to generate a reproducer we copy over the files and their
permission into to reproducer folder.
When replaying a reproducer, we load the VFS mapping and instantiate a
RedirectingFileSystem. The latter will transparently use the files
available in the reproducer.
I've tested this on two macOS machines with an artificial example.
Still, it is very likely that I missed some places where we (still) use
native file system calls. I'm hoping to flesh those out while testing
with more advanced examples. However, I will fix those things in
separate patches.

The new LLVM header is one line shorter than the old one, which lead to
some test failures. Ideally tests should rely on line numbers for
breakpoints or output, but that's a different discussion. Hopefully this
turns the bots green again.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This patch changes the way the reproducer is initialized. Rather than
making changes at run time we now do everything at initialization time.
To make this happen we had to introduce initializer options and their SB
variant. This allows us to tell the initializer that we're running in
reproducer capture/replay mode.
Because of this change we also had to alter our testing strategy. We
cannot reinitialize LLDB when using the dotest infrastructure. Instead
we use lit and invoke two instances of the driver.
Another consequence is that we can no longer enable capture or replay
through commands. This was bound to go away form the beginning, but I
had something in mind where you could enable/disable specific providers.
However this seems like it adds very little value right now so the
corresponding commands were removed.
Finally this change also means you now have to control this through the
driver, for which I replaced --reproducer with --capture and --replay to
differentiate between the two modes.
