e8a891b0 - [AArch64][Machine-Combiner] Split gather patterns into neon regs to multiple vectors (#142941)

[AArch64][Machine-Combiner] Split gather patterns into neon regs to multiple vectors (#142941) This changes optimizes gather-like sequences, where we load values separately into lanes of a neon vector. Since each load has serial dependency, when performing multiple i32 loads into a 128 bit vector for example, it is more profitable to load into separate vector registers and zip them. rdar://151851094
