I should mention I made one patch before based on the vectorizer code which did
detection of at least memset; it was while I was an intern at Apple. I posted
it and there was some review. And a few years back there was a paper at the
GCC summit about it and expanding it to memcpy. I don't know what happened to
that code though.
