Adds the ability to run the llvm test suite in-tree.

This was accomplished by building additional tools and hand-generating
several files that are auto-generated by the configuration system when
LLVM is built out-of-tree.  The LTO, Interpreter, and DebugInfo libraries
are now being compiled, and several source files were added to existing
compilation targets.

To run these tests you must first run build/envsetup.sh and have used
lunch to select a target.  You can then launch the test script by running:

cd $ANDROID_BUILD_TOP/external/llvm && ./android_test.sh
