invoking the array descriptor language hook. Initialize the
array_descr_info structure before calling the lang-hook.
(gen_descr_array_type_die): Use gen_type_die if not processing the main
type variant. Replace Fortran-specific code with generic one using
this new field. Add a GNAT descriptive type, if any. Output type
information for the array bound subrange, if any.

with column major ordering.

Add -malign-data={abi|compat,cachineline} to control how GCC aligns
variables. "compat" uses increased alignment value compatible with
GCC 4.8 and earlier, "abi" uses alignment value as specified by the
psABI, and "cacheline" uses increased alignment value to match the
cache line size. "compat" is the default.

They are never necessary, and they can cause problems when a
thunk is used to pass an unexported type from a different
package to a function defined in that package. The resulting
struct type may need to call the comparison routine from the
other package, which will fail because the type is not
exported. This will be bug492 in the master testsuite.
