Improve header information displayed with objdump -P for PE binaries.
* od-pe.c (targ_info): New array. (get_target_specific_info): New function. (decode_machine_number): Retire. Use get_target_specific_info instead. (is_pe_object_magic): Likewise. (dump_pe_file_header): Display more information. Rework layout to be similar to that from 'objdump -p'. Add code to handle larger than normnal AOUT headers.
