i965/fs/nir: Simplify 64-bit store_output

The swizzles weren't doing any good because swiz is just XYZW.  Also, we
were emitting an extra set of MOVs because shuffle_64bit_data_for_32bit
already does a MOV for us.  Finally, the temporary was only ever used
inside the inner loop so there's no need for it to actually be an array.
