[POWERPC] Import spu disassembly code into xmon This patch imports and munges the spu disassembly code from binutils. All files originated from version 1.1 in binutils cvs. * spu.h, spu-insns.h and spu-opc.c are unchanged except for pathnames. * spu-dis.c has been edited heavily: * use printf instead of info->fprintf_func and similar. * pass the instruction in rather than reading it. * we have no equivalent to symbol_at_address_func, so we just assume there is never a symbol at the address given.
