nv50/ir: copy joinAt when splitting both before and after
The current implementation only moves the joinAt when splitting after the given instruction, not before it. So if you have a BB with foo instr bar joinat and thus with joinAt set, we end up first splitting before instr, at which point the instr's bb is updated to the new bb. Since that bb doesn't have a joinAt set (despite containing one), when splitting after the instr, there is nothing to copy over. Since the joinat will be in the "split" bb irrespective of whether we're splitting before or after the instruction, move it over in either case.
