While adding spu disassembly support it struck me that we're actually
carrying quite a lot of code around, just to do disassembly in the case
of a crash.
While on large systems it's not an issue, on smaller ones it might be
nice to have xmon - but without the weight of the disassembly support.
For a Cell build this saves ~230KB (!), and for pSeries ~195KB.
We still support the 'di' and 'sdi' commands, however they just dump
the instruction in hex.
Move the definitions into a header to clean xmon.c just a tiny bit.

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.
