  [X86] Make deinterleave8bitStride3 use unary CreateShuffleVector

This patch makes X86InterleavedAccessGroup::deinterleave8bitStride3 use the unary CreateShuffleVector.

This is a continuation of D93923. There were a few missing replacements.

IIUC, this patch does not cause change in the generated programs' semantics because the
function inserts shufflevectors that only choose elements from the first vector.
