Summary: A simple genetic in-process coverage-guided fuzz testing library. I've used this fuzzer to test clang-format (it found 12+ bugs, thanks djasper@ for the fixes!) and it may also help us test other parts of LLVM. So why not keep it in the LLVM repository? I plan to add the cmake build rules later (in a separate patch, if that's ok) and also add a clang-format-fuzzer target. See README.txt for details. Test Plan: Tests will follow separately.
