* coff-rs6000.c (_bfd_xcoff_swap_aux_out): Use bfd_h_put_16 to
output x_tvndx as it is only two bytes wide.

* coff-rs6000.c (xcoff_howto_table): A modifiable branch-absolute
        reloc is 26 or 32 bits wide.

* coff-rs6000.c (_bfd_xcoff_rtype2howto): The bitsize is irrelevant
        for relocs that don't change anything.  Also look at the full
        6 bits of bitsize.
