  -----------
  Add support for fixed-point types (#129596)

This adds DWARF generation for fixed-point types. This feature is needed
by Ada.

Note that a pre-existing GNU extension is used in one case. This has
been emitted by GCC for years, and is needed because standard DWARF is
otherwise incapable of representing these types.
