Speed up objdump when displaying disassembly mixed with line number and source code information.
bfd * dwarf2.c (lookup_address_in_function_table): Return early if
there are no functions in the given comp unit, or if the high
address of the last function in the comp unit is less than the
desired address.
binutils * objdump.c (display_file): Add new parameter 'last_file'. If
last_file is true, do not call bfd_close at the end of the
function.
(main): Set the value of the last_file parameter when calling
display_file.
