It seems to me, that if vg were present in the xml, and honored by gdb, that
the xml for the rest of the registers *could* describe the maximum register
width as opposed to the current register width. At which point this wouldn't
need to be dynamic at all -- merely have a comment next to ARM_MAX_VQ that
changes must be reflected in the gdb xml file too. Which I expect to never happen.
But again, this is how gdb works today, so
