* dwarfread.c: Changes to match new dwarf.h. Remove
AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
and AT_is_external.

Some fields have a flag <name>_p that is set when the value of the
field is valid (I.E. we found a matching attribute in the DIE). Since
we may want to test for the presence of some attributes in the DIE,
such as AT_is_external, without restricting the values of the field,
such as AT_low_pc, without restricting the values of the field,
we need someway to note that we found such an attribute.
