I am fairly sure that there is usually no quicker way of transferring a bit state in less than 3 instructions, if you don't know the initial state.
On PWM applications, you may already know that the output is off when you come round to turn it on.
Also, you may be able to clear an entire register, then set individual bits. Each individual bit has two instructions to set it, but the overall number of instructions is less than if you cleared individual bits one at a time.
