Alan Modra 660df28acf Prefer object over notype symbols when disassembling

Changing objdump disassembly output like this always requires some
testsuite changes, with the avr and x64_64 changes simply due to
picking up better symbols, the whole point of the patch.

The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols
to STT_OBJECT, which objdump now chooses in preference to script
symbols.  The problem is that objdump looks at the first symbol in the
section being disassembled, and if object type, just dumps out bytes
rather than disassembling.  This results in new failures:

FAIL: JAL overflow 2
FAIL: undefined weak symbol overflow
FAIL: undefined weak symbol overflow (n32)
FAIL: undefined weak symbol overflow (n64)

So for mips-sgi-irix function symbols really do need to be function
type.  I fixed a few more than just the required minimum to avoid the
above test fails.

binutils/
	* objdump.c (compare_section): New static var.
	(compare_symbols): Sort by current section only.  Don't access
	symbol name out of bounds when checking for file symbols.
	Sort section symbols and object symbols.
	(find_symbol_for_address): Remove bogus debugging and section
	symbol test.
	(disassemble_data): Move symbol sort from here..
	(disassemble_section): ..to here.  Set compare_section.
