c6fe5670 - [AArch64][MachineCombiner] Combine sequences of gather patterns (#152979)

[AArch64][MachineCombiner] Combine sequences of gather patterns (#152979) Reland of #142941 Squashed with fixes for #150004, #149585 This pattern matches gather-like patterns where values are loaded per lane into neon registers, and replaces it with loads into 2 separate registers, which will be combined with a zip instruction. This decreases the critical path length and improves Memory Level Parallelism. rdar://151851094
