David L Kreitzer 01a057a0c4 Add a pass to optimize patterns of vectorized interleaved memory accesses for 
X86. The pass optimizes as a unit the entire wide load + shuffles pattern
produced by interleaved vectorization. This initial patch optimizes one pattern
(64-bit elements interleaved by a factor of 4). Future patches will generalize
to additional patterns.
