PR 28447: implement multiple parameters for .file on XCOFF
On XCOFF, ".file" pseudo-op allows 3 extras parameters to provide additional information to AIX linker, or its debugger. These are stored in auxiliary entries of the C_FILE symbol. bfd/ PR 28447 * coffcode.h (combined_entry_type): Add extrap field. (coff_bigobj_swap_aux_in): Adjust names of x_file fields. (coff_bigobj_swap_aux_out): Likewise. * coffgen.c (coff_write_auxent_fname): New function. (coff_fix_symbol_name): Write x_file using coff_write_auxent_fname. (coff_write_symbol): Likewise. (coff_write_symbols): Add C_FILE auxiliary entries to string table if needed. (coff_get_normalized_symtab): Adjust names of x_file fields. Normalize C_FILE auxiliary entries.
