DWARF: create a macro for max dimensions for array descr. lang. hook
The array descriptor language hook can hold the description of a limited
number of array dimensions. This macro will ease preventing overflow in
front-ends.
gcc/ada/ChangeLog:
* gcc-interface/misc.c (gnat_get_array_descr_info): When the
array has more dimensions than the language hook can handle,
fall back to a nested arrays description. Handle context-less
array types.
gcc/ChangeLog:
* dwarf2out.h (DWARF2OUT_ARRAY_DESCR_INFO_MAX_DIMEN): New macro.
(struct array_descr_info): Use it for the dimensions array's
size.
* dwarf2out.c (gen_type_die_with_usage): Check that the array
descr. language hook does not return an array with more
dimensions that it should.
