Unit tests for IntegerDivision. Currently, just a basic sanity check to ensure that the code was generated properly. Future work would be finding some way to test the actual result that would be computed.

This was always part of the VMCore library out of necessity -- it deals
entirely in the IR. The .cpp file in fact was already part of the VMCore
library. This is just a mechanical move.

I've tried to go through and re-apply the coding standard's preferred
header sort, but at 40-ish files, I may have gotten some wrong. Please
let me know if so.

I'll be committing the corresponding updates to Clang and Polly, and
Duncan has DragonEgg.

Thanks to Bill and Eric for giving the green light for this bit of cleanup.

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.

The TEST_F macros actually declare *subclasses* of the test fixtures.
Even if they didn't we don't want them to declare external functions.
The entire unit test, including both the fixture class and the fixture
test cases should be wrapped in the anonymous namespace.

This issue was caught by the new '-Winternal-linkage-in-inline' warning.

no uses then the phi and the instruction now get zapped (checked by the
unittest).

any instructions to DCE, so delete the test.

Also renamed J and JP to I and IP in RecursivelyDeleteDeadPHINode.
