89f76ce51d [lit] Improve logging with file redirection.
- This will cause lit to automatically include the first 1K of data in
   redirected output files when a command fails (previously if the command
   failed, but the main point of the test was, say, a `FileCheck` later on, then
   the log wasn't helpful in showing why the command failed).

bf67aefcd0 [lit] Improve readability of failing scripts.
- This only applies to scripts executed by the _internal_ shell script
   interpreter.

 - This patch reworks the log to look more like a shell transcript, and be less
   verbose (but in the interest of calling attention to the important parts).

Here is an example of the new format, for commands with/without failures and
with/without output:
```
$ true
$ echo hi
hi

$ false
note: command had no output on stdout or stderr
error: command failed with exit status 1

```

960b5867c5 Add "REQUIRES-ANY" feature test
Summary:
This patch adds a "REQUIRES-ANY" feature test that is disjunctive. This marks a test as `UNSUPPORTED` if none of the specified features are available.

Libc++ has the need to write feature test such as `// REQUIRES-ANY: c++98, c++03`  when testing of behavior that is specific to older dialects but has since changed.

30a91fe472 [lit][googletest] Handle upstream gtest output
Summary:
Upstream googletest prints "Running main() from gtest_main.cc" to stdout prior
to running tests. LLVM removed that print statement in r61540. If a user were
to use lit to run tests that use upstream googletest, however, lit
reports "Running main()" as an invalid test name.

To avoid such a failure, add an extra conditional to `formats/googletest.py`.
Also add tests to demonstrate the modified behavior.

6966456067 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.

ad637ba2fd 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.

d3bcf04e83 [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!

2111b5758f [LIT] Fix failing LIT tests
Summary:
I spend some time trying to get the LIT test suite passing. Here are the changes that I needed to make on my machine.

I made the following changes for the following reasons.

1. google-test.py: The Google test format now checks for "[  PASSED  ] 1 test." to check if a test passes.
2. discovery.py: The output appears in a different order on my machine than it did in the test.
3. unittest-adaptor.py: The output appears in a different order on my machine than it did in the test.
4. The classname is now formed differently in `getJUnitXML(...)`.

I'm not sure what is causing the output order to differ in discovery.py and unittest-adaptor.py. Does anybody have any thoughts?

708bc15ff0 Require python 2.7.
We were already requiring 2.5, which meant that people on old linux distros
had to upgrade anyway.

Requiring python 2.6 will make supporting 3.X easier as we can use the 3.X
exception syntax.

According to the discussion on llvmdev, there is not much value is requiring
just 2.6, we may as well just require 2.7.

   performance tests (or other tests which might want to record information
   beyond simple PASS/FAIL).
