Install the OCaml dynamic libraries in the 'stubdirs' directory rather
than the llvm subdirectory in order to fix running executables created
by ocamlc. Otherwise, the executables fail to run being unable to locate
the libraries (unless the LLVM directory is explicitly added to
LD_LIBRARY_PATH).
The staging directories are not altered since they work for our
development setup anyway, and installing into two directories would
unnecessarily make the code more complex.

By creating a dummy of this target in LLVMConfig.cmake, projects that can build against out-of-tree LLVM can freely depend on the target without needing to have conditionals for if LLVM is in-tree or out-of-tree.

Pass the values of CMAKE_C_FLAGS and CMAKE_C_FLAGS_${CMAKE_BUILD_TYPE}
as -ccopt to ocamlc. This enforces the specific flags used for the LLVM
build to be used for OCaml bindings as well, notably -O and -march
flags.
This also solves the issue of the user being unable to force specific
flags for OCaml bindings builds. Gentoo needs this to enforce -DNDEBUG
consistently between the LLVM build and the split OCaml bindings build.

Summary:
GetSVN.cmake currently takes one or two pairs of <source directory path,
name>, then attempts to get the remote repository URL and source control
revision of the repositories at those one or two paths.
It takes two pairs in order for Clang to get the revision of both
itself, and its dependency LLVM.
For projects that rely upon both LLVM and Clang (Apple's Swift is one
example, but there are others), GetSVN.cmake is used to fetch *three*
revisions: Swift, Clang, and LLVM.
To support this use case, change GetSVN.cmake: instead of taking one or
two pairs (specified via `FIRST_SOURCE_DIR`/`FIRST_NAME`, have it take a list
of pairs (`SOURCE_DIRS`/`NAMES`).
In order to allow Clang to migrate, have GetSVN.cmake support both sets
of arguments for now. The old arguments can be removed once Clang begins
using the new arguments, and Swift can follow when it updates its
copy of LLVM.
Test Plan:
1. Perform a clean build of Clang, verify that `clang --version` still
prints the correct LLVM and Clang revision information.
2. Modify Clang's CMake to use the new arguments, then perform another
clean build. `clang --version` should still print the correct
revision information.

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.

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.

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.
