Remove more unneeded files and directories from contrib/llvm. This

still allows us to build tblgen and clang, and further reduces the
footprint in the tree.

- - Move temp directory name into local test config.
-
- - Add --show-unsupported, don't show by default?
-
- - Finish documentation.
-
- - Optionally use multiprocessing.
-
- - Support llvmc and ocaml tests.
-
- - Support valgrind in all configs, and LLVM style valgrind.
-
- - Provide test suite config for running unit tests.
-
- - Support a timeout / ulimit.
-
- - Support "disabling" tests? The advantage of making this distinct from XFAIL
-   is it makes it more obvious that it is a temporary measure (and lit can put
-   in a separate category).

-class TerminalController:
-    """
-    A class that can be used to portably generate formatted output to
-    a terminal.  
-    
-    `TerminalController` defines a set of instance variables whose
-    values are initialized to the control sequence necessary to
-    perform a given action.  These can be simply included in normal
-    output to the terminal:
-
-        >>> term = TerminalController()
-        >>> print 'This is '+term.GREEN+'green'+term.NORMAL
-
-    Alternatively, the `render()` method can used, which replaces
-    '${action}' with the string required to perform 'action':
-
-        >>> term = TerminalController()
-        >>> print term.render('This is ${GREEN}green${NORMAL}')
-
-    If the terminal doesn't support a given action, then the value of
-    the corresponding instance variable will be set to ''.  As a
-    result, the above code will still work on terminals that do not
-    support color, except that their output will not be colored.
-    Also, this means that you can test whether the terminal supports a
-    given action by simply testing the truth value of the
-    corresponding instance variable:
-
-        >>> term = TerminalController()
-        >>> if term.CLEAR_SCREEN:
-        ...     print 'This terminal supports clearning the screen.'
-
-    Finally, if the width and height of the terminal are known, then
-    they will be stored in the `COLS` and `LINES` attributes.

-About
-=====
-
-Lit is a portable tool for executing LLVM and Clang style test suites,
-summarizing their results, and providing indication of failures. Lit is designed
-to be a lightweight testing tool with as simple a user interface as possible.
-
-
-Features
-========
-
- * Portable!
- * Flexible test discovery.
- * Parallel test execution.
- * Support for multiple test formats and test suite designs.
-
-
-Documentation
-=============
-
-The offical Lit documentation is in the man page, available online in the `LLVM
-Command Guide http://llvm.org/cmds/lit.html`_.
-
-
-Source
-======
-
-The Lit source is available as part of LLVM, in the `LLVM SVN repository
-<http://llvm.org/svn/llvm-project/llvm/trunk/utils/lit`_.
