Summary:
The issue with the python path is that the path to python on Windows can contain spaces. To make the tests always work, the path to python needs to be surrounded by quotes.
This change updates several configuration files which specify the path to python as a substitution and also remove quotes from existing tests.

larger timeout value. This really isn't very good because it will
still be susceptible to machine performance.
While we are here also fix a bug in validation of
`maxIndividualTestTime` where previously it wasn't checked if the
type was an int.

The program used to be used in `quick_then_slow.py` but that was
removed in r328702. The tests always run `slow.py` on its own but
this doesn't really test additional code so we'll just drop running
`slow.py` so the tests run faster.

The `shtest-timeout.py` test was failing intermittently. It looks like
the issue is that on a resource constrained system lit is unable to run
`quick_then_slow.py` twice and print out the messages the tests expects
within the one second timeout.
The underlying issue is that the test is dependent on the performance of
the host machine is a rather fragile way. This is due to hardcoding
timeout values and having assumptions that the host machine is able to
perform a certain amount of work within the hardcoded timeout values.
We could increase the timeout values but that doesn't really fix the
underlying issue. Instead this patch removes one of fragile assumptions
in the hope that this will be enough to fix the bots.
There are other fragile assumptions in this test (e.g. `quick.py` can be
executed in less than 1 second). If the bots continue to fail we'll have
to revisit this.

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!
