tests: Add an 'llvm-lit' tool (script), which gets generated as part of the
build and has the object build directory baked into it. This allows 'llvm-lit'
to properly find the information needed to run the test suite in all cases,
without requiring the user to have LLVM or 'lit' available in their PATH, for
example.
