LC bd9cf9ca11 AVX: Wire up lane helper for VPSHUFD/VPSHUFLW/VPSHUFHW
Lets the AVX implementation get all the optimizations that the SSE
variant has, reducing the overhead a little.

Even with the individual lane handling, this is still leagues better
than all of the individual inserts that are pretty beefy with SVE.

For example:

vpshufd ymm0, ymm1, 0b00000011

drops from 50 instructions to 9
