patch
Here is a try. Again, I just looked at the generated code on a couple examples,
which isn't very reliable...
expand_vec_perm_vperm2f128_vblend0 is already covered by
expand_vec_perm_vperm2f128_vblend1, but it is confusing to have a 3-instruction
function generate only 2.
I didn't do generic permutations with 4 instructions.
There is probably more that can be done with vshufp[sd].
