[POWERPC] Make xmon disassembly optional
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.
