nir/cf: clean up jumps when cleaning up CF nodes
We may delete a control flow node which contains structured jumps to other parts of the program. We need to remove the jump as a predecessor, as well as remove any phi node sources which reference it. Right now, the same problem exists for blocks that don't end in a jump instruction, but with the new API it shouldn't be an issue, since blocks that don't end in a jump must either point to another block in the same extracted CF list or not point to anything at all.
