DWARF: add a language hook to override types in debugging information
Many artificial types are introduced by GNAT in order to satisfy
constraints in GCC's internal trees or to generate optimal code. These
hide original types from sources and miss useful information in the
debugging information or add noise to it and make debugging confusing.
This change introduces a new language hook to give a chance to
front-ends to restore the source types in the debugging information.
This change also enhance the array descriptor language hook to handle
array-wide bit/byte stride. Some arrays may contain dynamically-sized
objects. Debuggers need for these a hint to know the size allocated for
each element, hence the need for the array-wide bit/byte stride.
The Ada front-end is enhanced to take advantage of both hooks when
-fgnat-encodings=minimal, in order to keep compatibility with GDB.

DWARF: handle variable-length records and variant parts
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.
