LLVM is always built; including it in LLVM_ENABLE_PROJECTS has no
effect, but since it's in LLVM_ALL_PROJECTS, we produce a confusing
message about it being disabled. Drop it from LLVM_ALL_PROJECTS to avoid
this. Pointed out by David Greene on the mailing list [1].

When LLVM_ENABLE_PROJECTS is set, CMake assumes the project
directories are all side-by-side. This is not always the case and
there's no reason to expect it if LLVM_EXTERNAL_<proj>_SOURCE_DIR is
set. Honor that setting if it exists and allow the build configuration
to continue.

We iterate over the list and only enable projects from that list that
are present in LLVM_ENABLE_PROJECTS and disable all other projects. Most
users will only specify clang in LLVM_ENABLE_PROJECTS and expect
clang-tools-extra to be implicitly enabled, so remove clang-tools-extra
from LLVM_ALL_PROJECTS so that it doesn't get disabled instead.

llvm-svn: 353354

Make LLVM_ALL_PROJECTS reflect all top-level directories in the monorepo
rather than an arbitrary subset. clang-tools-extra is technically
unnecessary since it gets enabled by clang, but having it there for
consistency shouldn't hurt either.

Previously, there were two different scripts for generating VCS headers:
one used by LLVM and one used by Clang and lldb. They were both similar,
but different. They were both broken in their own ways, for example the
one used by Clang didn't properly handle monorepo resulting in an
incorrect version information reported by Clang.

This change unifies two the scripts by introducing a new script that's
used from both LLVM, Clang and lldb, ensures that the new script
supports both monorepo and standalone SVN and Git setups, and removes
the old scripts.

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.

- Disable incremental linking by default. /INCREMENTAL adds extra thunks in the EXE, which makes execution slower.
- Set /MT (static CRT lib) by default instead of CMake's default /MD (dll CRT lib). The previous default /MD makes all DLL functions to be thunked, thus making execution slower (memcmp, memset, etc.)
- Adds LLVM_ENABLE_INCREMENTAL_LINK which is set to OFF by default.

Summary:
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.

This reverts commit rL346367 due to test error in compiler-rt.

llvm-svn: 346383

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.

This is just one place I missed swapping CMAKE_CONFIGURATION_TYPES with LLVM_ENABLE_IDE.

llvm-svn: 344568

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.
