* m68k-dis.c: (fpcr_names): Add % before all register names.
(reg_names): Likewise.
(print_insn_arg): Don't explicitly print % before register names.
Add % before register names in static array names. In case 'r',
print data registers as `@(Dn)', not `Dn@'. When printing a
memory address, don't print @# before it.
(print_indexed): Change base_disp and outer_disp from int to
bfd_vma. Print using MIT syntax, not mutant invalid Motorola
syntax. Sign extend 8 byte displacement correctly.
(print_base): Print using MIT syntax. Print zpc when appropriate.
Change parameter disp from int to bfd_vma.
