containing the data in the statement program header, and then
pass that to dwarf_decode_lines, which will pick up where that
left off. Be sure to clean up the `struct line_header' object.

argument, which is the type code for the new type.
(read_type): Rather than storing the type's type code here, pass
it as an argument to read_struct_type, and let that take care of
storing it. That way, we don't overwrite the original type code,
so read_struct_type can use it to decide whether we're overwriting
something we shouldn't.
