    nir: Turn imov/fmov of undef into undef
    Reverting the previous attempt at this a5502a721fd30fd resulted in
    the following Vulkan test failing.
    This time we use the num_components from the alu dest rather than
    num_inputs to the op to determine the size of the undef.

However both Ken and Jason seem to think this is just hiding a real bug so maybe we should keep this open?
