After refresh to latest LLVM & Clang and cleanup, nullptr.cpp runs and so do
the indexer tests. However, the

******************** TEST 'Clang :: Preprocessor/dependencies-and-pp.c'
FAILED ********************

Is still there. I run Python 2.6.5 and also have 2.4 installed (2.4 fails
almost all tests in Preprocessor/) Unfortunately I don't have Python 2.7
installed here (It's quite bleeding-edge, so I don't think most people
currently have it installed).

By some probing I figured out that the failure is with this line of
Preprocessor/dependencies-and-pp.c:

// RUN: diff %t.1 %t.2

Without it, Python doesn't throw the exception. So I did some printouts from
lit/TestRunner.py and it turns out it tries to use the diff.py script in the
Python installation directory (for my ActivePython 2.6.5 installation)
instead of gnuwin32's diff. Renaming diff.py makes the Preprocessor tests
run.

I'm not sure whether this is a problem with my personal setup or a more
general problem for lit.py, but I hope this description will be useful to
others.
So except the known image-info.m test, all clang tests pass.

Testing Time: 109.55s
********************
Failing Tests (1):
    Clang :: CodeGenObjC/image-info.m

  Expected Passes    : 2628
  Expected Failures  : 25
  Unsupported Tests  : 3
  Unexpected Failures: 1

Thanks for your help,
Eli
