There's quite a lot of references to Polly in the LLVM CMake codebase. However
the registration pattern used by Polly could be useful to other external
projects: thanks to that mechanism it would be possible to develop LLVM
extension without touching the LLVM code base.
This patch has two effects:
1. Remove all code specific to Polly in the llvm/clang codebase, replaicing it
with a generic mechanism
2. Provide a generic mechanism to register compiler extensions.
A compiler extension is similar to a pass plugin, with the notable difference
that the compiler extension can be configured to be built dynamically (like
plugins) or statically (like regular passes).
As a result, people willing to add extra passes to clang/opt can do it using a
separate code repo, but still have their pass be linked in clang/opt as built-in
passes.

Treat the flag `LLVM_ENABLE_ZLIB` as a tri-bool, `FORCE_ON` being `ON`,
and `ON` being an auto-detect. This is needed as many of the builders
enable the flag without having zlib available.
This patch adds a new IRTransformations directory to llvm/examples/. This is
intended to serve as a new home for example transformations/analysis
code used by various tutorials.
If LLVM_BUILD_EXAMPLES is enabled, the ExamplesIRTransforms library is
linked into the opt binary and the example passes become available.
To start off with, it contains the CFG simplifications used in the IR
part of the 'Getting Started With LLVM: Basics' tutorial at the US LLVM
Developers Meeting 2019.

It is sometimes useful to have the C++ standard library linked into the

onto systems that don't have a copy of stdlibc++ or libc++ installed.
This functionality should work with either GCC or Clang as the host

lldb recently added a tablegen tool. In order to properly cross compile
lldb standalone there needs to be a mechanism to generate the native

Until recently, Python_ADDITIONAL_VERSIONS was used to limit LLVM's
Python support to 2.7. Now that both LLVM and LLDB both support Python
3, there's no longer a need to put an arbitrary limit on this.
However, instead of removing the variable, r365692 expanded the list,
which has the (presumably unintentional) side-effect of expression
preference for Python 3.
Instead, as Michal proposed in the original code review, we should just
not set the list at all, and let CMake pick whatever Python interpreter
you have in your path.
This patch removes the Python_ADDITIONAL_VERSIONS variable in llvm,
clang and lld. I've also updated the docs with the default behavior and
how to force a different Python version to be used.

Summary:
CMake+Xcode doesn't seem to handle targets that only have object

Object libraries are generated whenever llvm_add_library is passed more
than one library type, which is now the default case for clang static
libraries (which generate STATIC and OBJECT libraries).

Summary:
It is useful to build with _XOPEN_SOURCE defined on AIX, enabling X/Open

bugs in the headers provided by the system and build compiler.
This patch adds the config to cmake to build with _XOPEN_SOURCE defined
on AIX with a few exceptions. Google Test internals require access to
platform specific thread info constructs on AIX so in that case we build
with _ALL_SOURCE defined instead. Libclang also uses header which needs
_ALL_SOURCE on AIX so we leave that as is as well.
We also add building on AIX with the large file API and doing CMake
header checks with X/OPEN definitions so the results are consistent with
the environment that will be present in the build.

LLVM_ENABLED_PROJECT and reconfigured it had no effect on what
projects were actually built. This was very confusing behaviour. The
reason for this is that the value of the `LLVM_TOOL_<PROJECT>_BUILD`
variables are already set.
The problem here is that we have two sources of truth:
* The projects listed in LLVM_ENABLE_PROJECTS.
* The projects enabled/disabled with LLVM_TOOL_<PROJECT>_BUILD.
At configure time we have no real way of knowing which source of truth
the user wants so we apply the following heuristic:
If the user ever sets `LLVM_ENABLE_PROJECTS` in the CMakeCache then that
is used as the single source of truth and we force the
`LLVM_TOOL_<PROJECT>_BUILD` CMake cache variables to have the
appropriate values that match the contents of the
`LLVM_ENABLE_PROJECTS`. If the user never sets `LLVM_ENABLE_PROJECTS`
then they can continue to use and set the `LLVM_TOOL_<PROJECT>_BUILD`
variables as the "source of truth".
The problem with this approach is that if the user ever tries to use
both `LLVM_ENABLE_PROJECTS` and `LLVM_TOOL_<PROJECT>_BUILD` for the same
build directory then any user set value for `LLVM_TOOL_<PROJECT>_BUILD`
variables will get overwriten, likely without the user noticing.
Hopefully the above shouldn't matter in practice because the
LLVM_TOOL_<PROJECT>_BUILD variables are not documented, but
LLVM_ENABLE_PROJECTS is.
We should probably deprecate the `LLVM_TOOL_<PROJECT>_BUILD`
variables at some point by turning them into to regular CMake
variables that don't live in the CMake cache.

Currently we can't install the modulemaps provided by LLVM, since they are not structured to support headers generated as part of the build (ex. `llvm/IR/Attributes.gen`).
This patch restructures the module maps in order to support installation.
Modules containing generated headers are defined in the new `module.extern.modulemap` file, and are referenced from the main `module.modulemap` using `extern module`. There are two versions of the `module.extern.modulemap` file; one used when building and another, `module.install.modulemap`, which is re-named during installation.
Users can opt-into module map installation using `-DLLVM_INSTALL_MODULEMAPS=ON`. The default value is `OFF` due to llvm.org/PR31905.

Make the check_include_file* macros honor CMAKE_REQUIRED_LIBRARIES. This
shouldn't cause any of the configuration checks to give different
results (and I did clean configures before and after this change and
confirmed that the resulting CMake caches were identical, though of
course that's just one machine). This suppresses a warning when building
with CMake 3.12 or later.
This doesn't suppress the warning in clang, because clang does its own
cmake_minimum_required call even when being built in-tree, and that
resets all policy settings. I'll address that separately.

Summary:
Code in config-ix tries to call `PYTHON_EXECUTABLE` to search for some
python modules but that variable isn't set until the moved chunk of
code that finds Python is called.
Reorder it so CMake can use PYTHON_EXECUTABLE

There are several places where we use CMAKE_CONFIGURATION_TYPES to determine if we are using an IDE generator and in turn decide not to generate some of the convenience targets (like all the install-* and check-llvm-* targets). This decision is made because IDEs don't always deal well with the thousands of targets LLVM can generate.
This approach does not work for Visual Studio 15's new CMake integration. Because VS15 uses a Ninja generator, it isn't a multi-configuration build, and generating all these extra targets mucks up the UI and adds little value.
With this change we still don't generate these targets by default for Visual Studio and Xcode generators, and LLVM_ENABLE_IDE becomes a switch that can be enabled on the VS15 CMake builds, to improve the IDE experience.
This is a re-land of r340435, with a few minor fix-ups. The issues causing the revert were addressed in r344218, r344219, and r344553.

Summary:
After fixing memory leaks in rL343362 and rL343733 the sanitizer builds are
clean and we should be good to build by default again.

There is a memory leak which is detected in some of the sanitizer builds.
MCSymbolWasm contains SmallVectors for holding signature information,
however MCContext doesn't run destructors for MCSymbols, so in cases
where the SmallVectors heap-allocate, the memory is leaked.

This makes WebAssembly build by default, rather than requiring
LLVM_EXPERIMENTAL_TARGETS_TO_BUILD!

The assertion in MCCodeView.cpp was resolved in r340878.
This reverts both r340905 and r340836, making benchmarks build by
default everywhere.

This simplifies installing all LLVM libraries when doing component
build; now you can include llvm-libraries in distribution components.

That resulted in the check-llvm-* targets not being avaliable
in the QtCreator-configured build directories.
Moreover, that was a clearly non-NFC change, and i can't find any review
for it.
This reverts commit rL340435.
