Makefiles, the CMake files in every other part of the LLVM tree, and
sanity.

This should also restore the output tree structure of all the unit
tests, sorry for breaking that, and thanks for letting me know.

The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages:

- No more weird directory stripping in the unittest macro, allowing it
  to be used more readily in other projects.
- No more directory prefixes on all the source files.
- Allows correct and precise use of LLVM's per-directory dependency
  system.
- Allows use of the checking logic for source files that have not been
  added to the CMake build. This uncovered a file being skipped with
  CMake in LLVM and one in Clang's unit tests.
- Makes Specifying conditional compilation or other custom logic for JIT
  tests easier.

It did require adding the concept of an explicit 'optional' source file
to the CMake build so that the missing-file check can skip cases where
the file is *supposed* to be missing. =]

This is another chunk of refactoring the CMake build in order to make it
usable for other clients like CompilerRT / ASan / TSan.

Note that this is interdependent with a Clang CMake change.

a helper function in CMake. This will allow us to share all of this
logic with Clang, and eventually CompilerRT.

facilities.

This was only used in one place in LLVM, and was used pervasively (but
with different code!) in Clang. It has no advantages over the standard
CMake facilities and in some cases disadvantages.

This was previously only done for executables and shared libraries, but not
for modules. As modules are essentially shared libraries (that need to be
dlopened explicitly), threating them the same as shared libraries seems
reasonable. This fixes the LLVM_BUILD_32_BITS build of Polly.

While making lld build under the tools directory I decided to refactor how this
works.

There is now a macro, add_llvm_external_project, which takes the name of the
expected subdirectory. This sets up two CMake options.

 * LLVM_EXTERNAL_${NAME}_SOURCE_DIR
     This is the path to the source. It defaults to
     ${CMAKE_CURRENT_SOURCE_DIR}/${name}.
 * LLVM_EXTERNAL_${NAME}_BUILD
     Enable and disable building the tool as part of LLVM.

I chose LLVM_EXTERNAL_${NAME} as a prefix so they all show up together in the
GUI.

This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.

Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

Passing -1 as the length of the desired substring was a new feature

in CMake a bit more handy. Previously we would get such charming
versions as the following for revision NNNN and commit-ish XXXXX:
  3.1svnsvn-rNNNN
  3.1svngit-svn-rNNNN
  3.1svngit-svn-XXXXX

The mechanism selecting betwene the latter two was particularly odd, and
didn't work with all of the ways git-svn repos are set up apparently. It
also misses an important point -- both the revision *and* the git commit
might be relevant when working on a local branch some distance from
mainline. The new logic does several things:

1) It strips the redundant initial 'svn'.
2) It always looks for a git-svn revision number base, and when found
   includes it in the version.
3) If the git commit-ish for the current HEAD is not exactly that
   revision number, it is also included.

The resulting strings should roughly be:
  3.1svn-rNNNN
  3.1git-svn-rNNNN
  3.1git-svn-rNNNN-XXXXX

Suggestions on formatting etc always welcome. =] I've only looked at the
LLVM version string here, not Clang's (yet).

Note that the commit-ish reported is *not* terribly accurate. It updates
when 'cmake' is run, not when the binary is built. Still, it may be
better than nothing, especially if people have fairly long-lived git
repos and branches. This is not a new limitation, just didn't want
anyone to be surprised.

one aspect of them by having them use the (annoying, if not broken)
proper library dependency model for adding the LLVMTableGen library as
a dependency. This could manifest as a link order issue in the presence
of separate LLVM / Clang source builds with CMake and a linker that
really cares about such things.

Also, add the Support dependency to llvm-tblgen itself so that it
doesn't rely on TableGen's transitive Support dependency. A parallel
change for clang-tblgen will be forthcoming.
