Summary: CompileUnit is a complicated class. Having it be implicitly convertible to a FileSpec makes reasoning about it even harder. This patch replaces the inheritance by a simple member and an accessor function. This avoid the need for casting in places where one needed to force a CompileUnit to be treated as a FileSpec, and does not add much verbosity elsewhere. It also fixes a bug where we were wrongly comparing CompileUnit& and a CompileUnit*, which compiled due to a combination of this inheritance and the FileSpec*->FileSpec implicit constructor.
