That was done with r0-89162-g11b08ee9118d10 (4.4.0)
I also have a start for self-DCE for the vectorizer. See PR116711 (I hope to
finish that up for GCC 16), it will improve compile time.
This is a generic bug without any other clear goal. I do think we need to
re-tuning of the gimple pipeline but I am not sure if there is any obvious way
right now. Plus we already had a few other re-tuning since GCC 4.4 too.
