Hi, this patch makes it possible to execute optimizations early (ie before IPA is performed).

I'd be curious what the existing prior art is in this area. Have you talked to Kenny Z. or Danny B. about this at all? I'm not oppposed, and I can certainly see how this would help; I'm just curious. I also wonder whether we should fix the in-and-out-of-SSA problem before putting this in; that seems like something that we're starting to run up against in multiple contexts, and going back and forth is pretty expensive in terms of both time and memory.
