lp_build_gather_elem_vec big-endian fix for 3x16 load

In reply to Roland's Comment 32:

Roland, thanks for the constructive feedback.  Here is what the patch
looks like now.

I don't disagree that this is messy, but it DOES resolve (most of) the
Piglit regressions.

I agree that the code in lp_bld_gather should work for 4x16 bit
vectors, but SOMETHING appears to have gone right already for 4x16 bit
vectors, as the only regressions seen had to do with 3x16 vectors.
