Requiring SSSE3 would also work for me personally, though I am not convinced
at all that the performance win over SSE2 would be worth dropping 2
generations of CPUs (SSE2, SSE3).
Requiring anything newer would exclude half (SSE4, AVX1) or all (AVX2) my
computers.

To be precise, Haswell is actually AVX2.
