A little helper class used to produce diagnostics.
This is constructed by the DiagnosticsEngine::Report method, and allows insertion of extra information (arguments and source ranges) into the currently "in flight" diagnostic. When the temporary for the builder is destroyed, the diagnostic is issued.
Note that many of these will be created as temporary objects (many call sites), so we want them to be small and we never want their address taken. This ensures that compilers with somewhat reasonable optimizers will promote the common fields to registers, eliminating increments of the NumArgs field, for example.

Copy constructor.
When copied, this "takes" the diagnostic info from the input and neuters it.
