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.
