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.

Once this function has been called, the DiagnosticBuilder object should not be used again before it is destroyed.

Conversion of DiagnosticBuilder to bool always returns true
.
This allows is to be used in boolean error contexts (where true
is used to indicate that an error has occurred), like:
