mtklein 036e1831e0 Add a bench to measure the best way to pack from int to uint16_t with SSE. 
I measured relative runtimes on my laptop:

   pack_int_uint16_t_ss…
   1036  …e41 1x  …se3 1.01x  …e2_b 3.01x  …e2_a 3.02x

I've run into Clang problems with the actual _mm_packus_epi32 instruction, I think,
so I'm going to exercise a little cowardice and leave that option disabled for now.

The ssse3 version probably looks a little faster than it will be in practice.
We'll usually need to load its mask, which here is hoisted out of the bench loop.

The two sse2 variants are close enough in speed that I'm tie breaking them on other
concerns: the <<16, >>16 version doesn't need any scratch registers or to load any
constants, so it wins.
