Debugging compiler failures is critical for developers. This change enhances the dump messages produced by the SLP (Superword-Level Parallelism) vectorizer when it fails to compute lane extraction insertion points. The improved output in tree-vect-slp.cc aims to provide clearer insights into the failure, aiding developers in diagnosing issues with vectorization.
