dwfl_getsrclines would always fail, even when lines were found.
dwarf_decl_file, and other functions relying on srcfiles or srclines would
fail for DIEs in partial_units because stmt_lists on partial_units
were ignored.
Note that dwz contained a bug which makes things fail in __libdw_formptr
for DW_AT_stmt_list with a bogus DW_FORM even with these fixes.
