Support unordered .debug_info references to .debug_ranges.
	* dwarf.c (struct range_entry, range_entry_compar): New.
	(display_debug_ranges): Remove variables last_offset, first, j,
	seen_first_offset, use_debug_info and next.  New variables
	range_entries and range_entry_fill.  Create the sorted copy
	range_entries.  Remove the FIXME error on detected unordered references.
	* dwarf.h (debug_info <range_lists>): New comment.

binutils/testsuite/
	* binutils-all/objcopy.exp (testranges): New test.
	* binutils-all/testranges.d, binutils-all/testranges.s: New files.
