This changes adds support for building runtimes for multiple
different targets using LLVM runtimes directory.
The implementation follow the model used already by the builtins
build which already supports this option. To specify the runtimes
targets to be built, use the LLVM_RUNTIME_TARGETS variable, where
the valuae is the list of targets to build runtimes for. To pass
a per target variable to the runtimes build, you can set
RUNTIMES_<target>_<variable> where <variable> will be passed to the
runtimes build for <target>.
Each runtime target (except for the default one) will be installed
into lib/<target> subdirectory. Build targets will be suffixed with
the target name.

Summary:
This is like the LLVM_TOOLS_INSTALL_DIR option, but for the utils
that are installed when the LLVM_INSTALL_UTILS. This option
defaults to 'bin' to remain consistent with the current behavior, but
distros may want to install these to libexec/llvm.

CMake emits build targets as relative paths (from build.ninja) but Ninja doesn't identify absolute path (in *.d) as relative path (in build.ninja).
So, let file names, in the command line, relative from ${CMAKE_BINARY_DIR}, where build.ninja is.
Note that tblgen is executed on ${CMAKE_BINARY_DIR} as working directory.

This commit causes LLVM_USE_SANITIZER to now accept the "Leaks" option. This
will cause cmake to pass in -fsanitize=leak in all of the appropriate places.

leaks.

No behavior is changed if LLVM_TARGET_TRIPLE_ENV is blank or undefined.
If LLVM_TARGET_TRIPLE_ENV is "TEST_TARGET_TRIPLE" and $TEST_TARGET_TRIPLE is not blank,
llvm::sys::getDefaultTargetTriple() returns $TEST_TARGET_TRIPLE.
Lit resets config.target_triple and config.environment[LLVM_TARGET_TRIPLE_ENV] to change the default target.
Without changing LLVM_DEFAULT_TARGET_TRIPLE nor rebuilding, lit can be run;
TEST_TARGET_TRIPLE=i686-pc-win32 bin/llvm-lit -sv path/to/test/

For the case when LLVM_OPTIMIZED_TABLEGEN is ON (enables LLVM_USE_HOST_TOOLS),
we need both _TABLEGEN_TARGET and _TABLEGEN_EXE in the DEPENDS list
to have .inc files rebuilt on a tablegen change, as cmake does not propagate
file-level dependencies of custom targets.
We could always have just one dependency on both the target and
the file, but the 2 cases would produce cleaner cmake files.

Summary:
Reverse iteration can be turned on, by default, by setting -DLLVM_REVERSE_ITERATION:BOOL=ON during cmake.
With this enabled, we can uncover lots of cases of non-determinism in codegen by simply running our tests (without any other change).
We can then setup a buildbot which will have this turned on by default. Initially, a lot of unit tests will fail in this configuration.
Once we start fixing non-determinism issues, we can gradually make this a blocker for patches.

Summary:
This patch adds a very simple linker script to version the lib's symbols
and thus trying to avoid crashes if an application loads two different
LLVM versions (as long as they do not share data between them).
Note that we deliberately *don't* make LLVM_5.0 depend on LLVM_4.0:
they're incompatible and the whole point of this patch is
to tell the linker that.
Avoid unexpected crashes when two LLVM versions are used in the same process.

This is a magic header file supported by the build system that provides a
single definition, LLVM_REVISION, containing an LLVM revision identifier,
if available. This functionality previously lived in the LTO library, but
I am moving it out to lib/Support because I want to also start using it in
lib/Object to create the IR symbol table.
This change also fixes a bug where LLVM_REVISION was never actually being
used in lib/LTO because the macro HAS_LLVM_REVISION was never defined (it
was misspelled as HAVE_SVN_VERSION_INC in lib/LTO/CMakeLists.txt, and was
only being defined in a non-existent file Version.cpp).
I also changed the code to use "git rev-parse --git-dir" to locate the .git
directory, instead of looking for it in the LLVM source root directory,
which makes this compatible with monorepos as well as git worktrees.

CMake variable LLVM_DEFINITIONS collects preprocessor definitions provided
for host compiler that builds llvm components. A function
add_llvm_definitions was introduced in AddLLVMDefinitions.cmake to keep
track of these definitions and was intended to be a replacement for CMake
command add_definitions. Actually in many cases add_definitions is still
used and the content of LLVM_DEFINITIONS is not actual now. On the other
hand the current version of CMake allows getting set of definitions in a
more convenient way. This fix implements evaluation of the variable by
reading corresponding cmake property.

Summary:
clang-cl understands the GCC-style -W[no-]foo flags, and for the most
part ignores MSVC -wd flags. So, let's pass the curated set of warning
flags we use on Unix on Windows. We can also stop passing /W4 -wd*,
which for the most part corresponds to -Wall -Wextra with a bunch of
flags that we mostly ignore.
I had to disable -Wnon-virtual-dtor on Windows, because it fires on
every COM class ever. I filed PR32286 to fix this.
So far I've only found two instances of -Wstring-conversion in the
WinASan code, which I'll fix. Other than that we seem clean.

Summary:
The add_tablegen macros defines its own install target, and it was also calling
add_llvm_utility which adds another install target.
Configuring with -DLLVM_TOOLS_INSTALL_DIR set to something other than
'bin' along with -DLLVM_INSTALL_UTILS=ON was causing llvm-tablgen
to be installed to two separate directories.

Summary:
Fix a few problems in VersionFromVCS.cmake to make it more reliable:
- Stop using git svn info to retrieve the svn revision. I am unable to
determine what the svn revision returned by this command means.
During my testing this command returned a revision from a month
ago which was not the HEAD of any of my local branches.
Also, this revision was never actually added to the version string due
to a typo in the script. All it was used for was to reject the
revision number returned by git svn find-rev HEAD when the revision
numbers didn't match.
- Populate GIT_COMMIT even when we detect a git repo without any
svn information.

Summary: With clang-cl gaining support for link-time optimization, we can now enable builds using LTO when using clang-cl and lld on Windows. To do this, we must not pass the -flto flag to the linker; lld-link does not understand it, but will perform LTO automatically when it encounters bitcode files. We also don't pass /Brepro when using LTO - the compiler doesn't generate object files for LTO, so passing the flag would only result in a warning about it being unused.

LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects
to correctly link the threading library when needed. Unfortunately
`PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed
and therefore can't be used when configuring out-of-tree builds. This causes
such builds to fail since `pthread` isn't being correctly linked.
This patch attempts to fix that problem by renaming and exporting
`LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB`
because It seemed likely to cause collisions with downstream users of
`LLVMConfig.cmake`.
