The powerpc xml files contained a hack--an empty, non-existent register--for getting the register numbers to line up for newer (XML-aware) and older (non-XML-aware) GDB. While this hack worked in some cases, it didn't work in all cases, notably when the user used `finish' or `continue': GDB would attempt to read the non-existent register and QEMU would complain. This patch fixes things up properly. Instead of inserting a fake register, we explicitly declare the floating-point and SPE registers to start at 71. This action accomplishes the same thing as the nasty hack, except that now GDB never tries to fetch the non-existant register 70.
