It is kinda crazy to have llvm/include and llvm/lib/Target in the include path for every tablegen invocation for every tablegen-like tool.
This patch removes those flags from the tablgen function that is called everywhere by instead creating a variable LLVM_TABLEGEN_FLAGS which is setup in the LLVM source directories.
This removes TableGen.cmake's dependency on LLVM_MAIN_SRC_DIR, and LLVM_MAIN_INCLUDE_DIR.

The old implementation of add_llvm_tool_symlink could fail in odd ways when building out of tree. This version solves that problem by not using the LLVM_* variables, and instead reaeding the target's properties.

Summary:
The motivation for this is to enable correct detection of dlopen() on Android.
Android does not provide a static version of libdl, so if we add the -static flag
after performing the check, it will succeed even though subsequent link steps
will fail. With this change we correctly detect the absence of libdl in a
LLVM_BUILD_STATIC build on Android.
The link itself still does not succeed because the code does not check the result
of this check properly, but I plan to fix that in a separate change.

This patch adds an option to the build system LLVM_DEPENDENCY_DEBUGGING. Over time I plan to extend this to do more complex verifications, but the initial patch causes compile errors wherever there is missing a dependency on intrinsics_gen.
Because intrinsics_gen is a compile-time dependency not a link-time dependency, everything that relies on the headers generated in intrinsics_gen needs an explicit dependency.

Summary:
Set _install_rpath to CMAKE_INSTALL_RPATH if it is defined, so that eventually
INSTALL_RPATH is set to CMAKE_INSTALL_RPATH.
The "if(NOT DEFINED CMAKE_INSTALL_RPATH)" was missing a corresponding else
clause.
This also cleans up the fix made in r285908.

r285714 made it so that when CMAKE_INSTALL_RPATH is set _install_rpath is not
set, but that means INSTALL_RPATH gets set to an empty string which isn't what

The RFC proposal sent to increase the minimum required GCC version
to 4.8 received a lot of support. See the following thread:
http://lists.llvm.org/pipermail/llvm-dev/2016-October/105955.html,
This patch implements that by updating the docs. I believe the
references to libstdc++ 4.7 issues can be removed as well, please
let me know if that is not the case or if they should be updated
a different way.

Make LIT_COMMAND configurable, use source tree only when actually
available and extend the default search to other common executable names
'lit.py' and 'lit', in order to increase uniformity between all LLVM
projects and support using installed lit.
Changing the conditional used to determine whether in-tree or external
lit is being used covers the case when LLVM_MAIN_SRC_DIR is defined but
does not exist (anymore). In this case, the functions falls back to
looking for installed lit rather than attempting to use a non-existing
path. The same conditional is used in clang already.
Making LIT_COMMAND a cache variable in case the source tree variant is
used serves two purposes. Firstly, it increases uniformity between
the two branches since find_program() implicitly makes LIT_COMMAND
a cache variable. Secondly, it allows overriding the lit executable used
to run the tests when the LLVM source tree is provided. Gentoo is
planning to use this to use installed (and byte-compiled) lit instead of
re-compiling it in every LLVM project.
Extending default search is meant to increase uniformity between
different LLVM projects. The 'lit.py' name is already used by a few of
them, and 'lit' is the name used by utils/lit/setup.py when installing.

Reintroduce versioning of shared libraries via SOVERSION, addressing
the issues with the previous design, since Gentoo is relying
on shared-split install of LLVM. The SOVERSIONs were originally
introduced in r229720 for all libraries, and removed in r252093 in favor
of custom SONAME. As far as I understand, the major concern with the old
versioning was that the used versions were incompatible with ldconfig.
Having considered that, this commit introduce SOVERSIONS with the
following considerations:
1. SOVERSIONs are formed of major & minor version concatenated -- i.e.
for 4.0 its .so.40. This matches the common practice where the first
version number indicates ABI breakage, and therefore fixes the issues
with ldconfig. Additionally, VERSION with the remaining verion
components appended is used, however this is not strictly necessary.
2. The versioning is only applied to libraries with no explicit SONAME
specified -- i.e. it won't apply to libLLVM but only to the split
libraries. It will also apply to libraries installed by the subprojects.
3. The versioning is only done on *nix systems, Darwin excluded. This
matches the current use of SONAME.

Revert the change in r283029 (and the fixup in r283033) due to buildbot
breakage. The fixup is ineffective for the bots that do not force clean
build since the wrong value is already cached in CMakeCache.txt.
Reverting it should result in the cache variable being removed
and therefore it should be possible to re-introduce it after all
buildbots build this revision.

Install the OCaml interface .mli files. Those files were most likely
omitted because they are input files for the compiled .cmi files.
However, installing them is reasonable since -- unlike .cmi files --
they are human-readable.

Add a OCAML_INSTALL_PATH variable that can be used to control
the install path for OCaml libraries. The new variable defaults to
${OCAML_STDLIB_PATH}, i.e. the OCaml library path obtained from
the OCaml compiler. Install libraries into "llvm" subdirectory.
This fixes two issues:
1. OCaml library directories differ between systems, and 'lib/ocaml' is
incorrect e.g. on amd64 Gentoo where OCaml is installed
in 'lib64/ocaml'. Therefore, obtain the library path from the OCaml
compiler using 'ocamlc -where' (which is already used to set
OCAML_STDLIB_PATH), which is the method used commonly in OCaml packages.
2. The top-level directory is reserved for the standard library, and has
precedence over local directory in search path. As a result, OCaml
preferred the files installed along with previous LLVM version over the
source tree when building a new version, resulting in two versions being
mixed during the build. The new layout is used commonly by other OCaml
packages, and findlib is able to find the LLVM libraries successfully.
