Why libfirm? It seems to only have x86 and sparc backends, and no
windows support?

But that essentially means redoing most of execQual's current code in IR
- or do you want to do that via 1) above?  As long as the preparation
code (which is currently intermixed with the execution phase) isn't
separated, that means pulling essentially the whole backend given that
we do catalog lookups and everything during that phase.

Are you planning to support this to postgres proper?
