[Liftoff] Avoid redundant reg list in register moves We currently hold the register list for {move_src_regs_} in the {StackTransferRecipe} class, and only compute src use counts for executing the moves. Since the use counts and the register list are redundant, just compute the use counts right away, and get rid of the register list. This saves one iteration of the register list in {ExecuteMoves}.
