This commit adds a new test case to verify a fix for bug PR110935 in the GCC tree optimization passes. The bug, which affected vectorization or SLP (Superword Level Parallelism) optimizations, was resolved in GCC 16. The new test case ensures that this specific optimization issue does not reappear.
