Fix for the complaint observed when symbol reading due to unsupported .debug_names form
Following complaint is observed with the executable compiled with -gdwarf-5
and -gpubnames flags - "During symbol reading: Unsupported .debug_names form
DW_FORM_ref4". This is the form corresponding to DW_IDX_die_offset attribute.
This patch fixes this complaint. Tested with clang 10.0.0. Test case used -
int main()
{
int sum,a,b;
sum = a + b;
return sum;
}
clang -gdwarf-5 -gpubnames test.c -o test.out
gdb -q test.out -ex "set complaints 1" -ex "start"

PR symtab/25952
* read.c (dw2_debug_names_iterator::next): Handle DW_FORM_ref*
and DW_IDX_die_offset. If there is no compilation unit attribute in
the index entry, then there is a single CU. Return the CU at O index
of compilation unit vector.
