least).

 - Move CMake to using the new test runner.

 - Switch Makefiles to use the lit.site.cfg.in template.

 - Remove explicit --path arguments, instead this gets written into the site
   configuration. This means running lit from the command line should use the
   exact same configuration as is used in 'make test', assuming it can find the
   site configuration file. You still need to run 'make test' (or the cmake
   build target equivalent) at least once.

 - MultiTestRunner will eventually be renamed to 'lit', for LLVM integrated
   tester/testing. This has the pros of being pronouncable and short.

 - "Project" level configuration lives in 'lit.cfg', which is also what lit uses
   to find the root testing directory in some cases. This can be overridden for
   use in project files which want to precisely specify where things are.

 - TestRunner.py is not longer able to be invoked directly.
 
 - Moved some code to Util.py.

 - Introduced a configuration object.

 - Cleaned up --help, removed a few not-very-useful options.

 - Tried not to break anything that works. :)
