Dan Liew c754ace22f Revert "Teach the CMake build system to run lit's test suite. These can be run"
This reverts r257221.

This caused several build bot failures

* It looks like some of the tests don't work correctly under Windows
* It looks like the lit per test timeout tests fail

So I'm reverting for now. Once the above failures are fixed running
lit's tests can be enabled again.

Dan Liew 9d49638f44 Teach the CMake build system to run lit's test suite. These can be run
directy with ``make check-lit`` and are run as part of
``make check-all``.

In principle we should run lit's testsuite before testing LLVM using lit
so that any problems with lit get discovered before testing LLVM so we
can bail out early.  However this implementation (``check-all`` runs all
tests together) seemed simpler and will still report failing lit tests.

Note that the tests and the configured ``lit.site.cfg`` have to be
copied into the build directory to avoid polluting the source tree.

Dan Liew 7574241053 [lit] Implement support of per test timeout in lit.
This should work with ShTest (executed externally or internally) and GTest
test formats.

To set the timeout a new option ``--timeout=`` has
been added which specifies the maximum run time of an individual test
in seconds. By default this 0 which causes no timeout to be enforced.

The timeout can also be set from a lit configuration file by modifying
the ``lit_config.maxIndividualTestTime`` property.

To implement a timeout we now require the psutil Python module if a
 timeout is requested. This dependency is confined to the newly added
 ``lit.util.killProcessAndChildren()``. A note has been added into the
 TODO document describing how we can remove the dependency on the
 ``pustil`` module in the future. It would be nice to remove this
 immediately but that is a lot more work and Daniel Dunbar believes it is
better that we get a working implementation first and then improve it.

To avoid breaking the existing behaviour the psutil module will not be
imported if no timeout is requested.

The included testcases are derived from test cases provided by
 Jonathan Roelofs which were in an previous attempt to add a per test
 timeout to lit (http://reviews.llvm.org/D6584). Thanks Jonathan!
