This should get a documentation comment describing the class.  You should mention that, like `APSInt`, it carries all of the semantic information about the value's type (width, signed-ness, saturating-ness, etc.), but by design it does not carry the original C type — among other reasons, so that it can more easily be moved to LLVM should fixed-point types gain native IR support.
