intel/fs: shuffle_from_32bit_read for 64-bit do_untyped_vector_read

Browse Source 
do_untyped_vector_read is used at load_ssbo and load_shared.

The previous MOVs are removed because shuffle_from_32bit_read
can handle storing the shuffle results in the expected destination
just using the proper offset.
