nir: move ALU instruction before the jump instruction
opt_split_alu_of_phi moves ALU instruction to the end of continue block.
But if the continue block ends with a jump instruction (an explicit
"continue" instruction) then the ALU must be inserted before the jump,
as it is illegal to add instructions after the jump.
