[PATCH] Add .clang-tidy configuration file to provide LLVM-optimized defaults for clang-tidy.

[Daniel Jasper]

Do we really need a separate file for Clang? Shouldn't D5236 suffice as Clang is always checked out into LLVM?

On the other hand, I would add files containing "Checks: '-*'" into the test/ directories of both. Mosts test won't be (and don't need to be) clang-tidy clean.
