Introduce a pure virtual clone() method to DiagnosticConsumer, so that
we have the ability to create a new, distict diagnostic consumer when
we go off and build a module. This avoids the currently horribleness
where the same diagnostic consumer sees diagnostics for multiple
translation units (and multiple SourceManagers!) causing all sorts of havok.
