patch
With this one, all V4DF shuffles on one vector are done in at most 3
instructions (and are correct). Doing V8SF at the same time was getting
confusing so I dropped it for the last 2 functions, which end up looking almost
like: "if the pattern is 0112 do this, if it is 0130 do that, etc".
I didn't check if all the functions are still used by at least one pattern...
Note: my access to an avx machine is not sufficient to submit a patch, so feel
free to take pieces of this and modify/test/submit them (I have a copyright
assignment).
