Enhance the DWARF back-end to emit proper descriptions for
variable-length records as well as variant parts in records.
In order to achieve this, generate DWARF expressions ("location
descriptions" in dwarf2out's parlance) for size and data member location
attributes. Also match QUAL_UNION_TYPE data types as variant parts,
assuming the formers appear only to implement the latters (which is the
case at the moment: only the Ada front-end emits them).
Note that very few debuggers can handle these descriptions (GDB does not
yet), so in order to ease the the transition enable these only when
-fgnat-encodings=minimal.
