Add an InstSimplify for repetitive array expressions

I noticed in https://github.com/rust-lang/rust/pull/135068#issuecomment-2569955426 that GVN's implementation of this same transform was quite profitable on the deep-vector benchmark. But of course GVN doesn't run in unoptimized builds, so this is my attempt to write a version of this transform that benefits the deep-vector case and is fast enough to run in InstSimplify.

The benchmark suite indicates that this is effective.
