[PATCH] MATCH: Optimize `VEC_SHL_INSERT (dup (A), A)` to just `dup (A) [PR116075]

It was noticed if we have `.VEC_SHL_INSERT ({ 0, ... }, 0)` it was not being simplified to just `{ 0, ... }`. This was generated from the autovectorizer (maybe even on accident, see PR tree-optmization/116081). This adds a few SVE testcases to see if this is optimized since the auto-vectorizer or
