cmake_minimum_required(VERSION) calls cmake_policy(VERSION),
which sets all policies up to VERSION to NEW.
LLVM started requiring CMake 3.13 last year, so we can remove
a bunch of code setting policies prior to 3.13 to NEW as it
no longer has any effect.

In lldb, explicitly set the "option() honors normal variables" CMake policy. This applies for
standalone lldb builds and matches what llvm, clang, etc do. This prevents potentially unwanted
clearing of variables like `LLVM_ENABLE_WARNINGS`, and also prevents unnecessary build warnings.

Separate the CMake logic for Lua and Python to clearly distinguish
between code specific to either scripting language and the code shared
by both.
What this patch does is:
- Move Python specific code into the bindings/python subdirectory.
- Move the Lua specific code into the bindings/lua subdirectory.
- Add the _python suffix to Python specific functions/targets.
- Fix a dependency issue that would check the binding instead of
whether the scripting language is enabled.
Note that this patch also changes where the bindings are generated,
which might affect downstream projects that check them in.

Move the finish_swig logic into a function in the bindings directory. By
making this a function I can reuse the logic internally where we ship
two Python versions and therefore need to finish the bindings twice.
The `intrinsics_gen` target exists in the CMake exports since r309389
(see LLVMConfig.cmake.in), hence projects can depend on `intrinsics_gen`
even it they are built separately from LLVM.

... and include it from the main CMakeLists.txt instead of including the
utility subdirectories directly. This is consistent with the other
subdirectories and limits the scope of future changes.
All the code required to generate the language bindings for Python and
Lua lives under scripts, even though the majority of this code aren't
scripts at all, and surrounded by scripts that are totally unrelated.
I've reorganized these files and moved everything related to the
language bindings into a new top-level directory named bindings. This
makes the corresponding files self contained and much more discoverable.

Require a newer CMake on Windows to use the Python3 support that is
packaged in CMake. This version is able to check both 32-bit and 64-bit
versions and will setup everything properly without the user needing to
specify PYTHON_HOME. This enables building lldb's python bindings on
Windows under Azure's CI again.
Previously, SWIG was only a hard dependency if python bindings were
enabled.
Since bf03e17c57, scripts/CMakeLists.txt
is included unconditionally, while that file adds the hard dependency
on SWIG.
Instead, only include that file if either python or lua bindings are
enabled.
This simplifies the CMake logic for adding the Python examples to the
Python package. It unifies the use of create_python_package by adding
the NOINIT option and removes the `target` argument, which is always
`finish_swig`.

The LLDB_TEST_BUILD_DIRECTORY variable only matters to the different
test suites. Therefore they belong in test/CMakeLists.txt rather than
the top-level CMakeLists.txt.
As the name suggests, the LLDB test dependencies only matter to the
different test suites. Therefore they belong in test/CMakeLists.txt
rather than the top-level CMakeLists.txt.
CMake allows you to set a custom CXX compiler for the API test suite.
However, this variable is never used, because dotest uses the same
compiler to build C and CXX sources.
I'm not sure if this variable was added with the intention of supporting
a different compiler or if this is just a remnant of old functionality.
Given that this hasn't been working for a while, I assume it's safe to
remove.

Summary:
This is another attempt of D67993.
This change removed hard coded relative paths. This way we can generate correct result when get_python_lib() returns a different path, or LLDB_PYTHON_RELATIVE_PATH is specified directly.
By moving things out of python, we are also able to correctly process more cross compile situations. E.g. .pyd vs .so for Windows.

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.

I often use `ninja lldb-test-deps` to build all the test dependencies
before running a subset of the tests with `lit --filter`. This
functionality seems to break relatively often because test dependencies
are tracked in an ad-hoc way acrooss cmake files. This patch adds a
helper function `add_lldb_test_dependency` to unify test dependency
tracking by adding dependencies to lldb-test-deps.

Based on mgorny@'s D67890
There are 3 places where python site-package path is calculated
independently:
1. finishSwigPythonLLDB.py where files are written to site-packages.
2. lldb/scripts/CMakeLists.txt where site-packages are installed.
3. ScriptInterpreterPython.cpp where site-packages are added to
PYTHONPATH.
This change creates the path once and use it everywhere. So that they
will not go out of sync.
Also it provides a chance for cross compiling users to specify the right
path for site-packages.

Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.
This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

Given that LLDB_TEST_USE_CUSTOM_C_COMPILER and LLDB_TEST_C_COMPILER are
both set at configuration time, I don't really see the point of having
both. This patch simplifies things and uses the custom C/C++ compiler
when the variable is set, and uses the default one when it's not set.
The variable can be unset by passing -ULLDB_TEST_C_COMPILER to CMake.

Summary:
When building with modules we currently fail randomly to build LLDB's modules and get error messages like below:
```
In file included from <module-includes>:1:
In file included from llvm-project/llvm/include/llvm/IR/Argument.h:18:
llvm-project/llvm/include/llvm/IR/Attributes.h:74:14: fatal error: 'llvm/IR/Attributes.inc' file not found

...

llvm-project/lldb/source/Plugins/ABI/SysV-arm/ABISysV_arm.h:12:10: fatal error: could not build module 'lldb_Wrapper'
```
The reason for this is that our source files can include Clang headers which in turn include files like Attributes.inc which
are generated by intrinsics_gen. However, it seems Clang can't express this dependency in its CMake code, so intrinsics_gen
is actually not guaranteed to be built before we start parsing LLDB source files and Clang headers. Clang worked around this
by letting all libraries depend on intrinsics_gen, which at least lets their builds pass.
As I haven't figured out how to solve these dependencies properly and I want to get the LLDB+Modules build green,
I suggest we copy Clang's hack until we figure out how to get Clang's dependencies right.

Summary:
The main CMake file don't have a project() call. In this case, cmake will run a dummy project(Project ) at the very beginning. Even before cmake_minimum_required. And a series of compiler detections will be triggered.
This is problematic if we depends on some policy to be set. E.g. CMP0056. try_compile will fail before we have a chance to do anything.

Property definitions are currently defined in a PropertyDefinition array
and have a corresponding enum to index in this array. Unfortunately this
is quite error prone. Indeed, just today we found an incorrect merge
where a discrepancy between the order of the enum values and their
definition caused the test suite to fail spectacularly.
Tablegen can streamline the process of generating the property
definition table while at the same time guaranteeing that the enums stay
in sync. That's exactly what this patch does. It adds a new tablegen
file for the properties, building on top of the infrastructure that
Raphael added recently for the command options. It also introduces two
new tablegen backends: one for the property definitions and one for
their corresponding enums.
It might be worth mentioning that I generated most of the tablegen
definitions from the existing property definitions, by adding a dump
method to the struct. This seems both more efficient and less error
prone that copying everything over by hand. Only Enum properties needed
manual fixup for the EnumValues and DefaultEnumValue fields.
