If `UseSectionsAsReferences == true`, `DwarfCompileUnit` do not define a separate label at the beginning of the unit and `getLabelBegin()` cannot be used. To reference the CU, the section symbol and the offset in the debug info section should be used instead.

This fixes a crash in `llvm/test/DebugInfo/Generic/2010-04-19-FramePtr.ll` when NVPTX is set as a default target.
