Actually, as far as I can remember, WHIRL isn't that different
from suitably chosen tree nodes.
And in the SGI compiler, WHIRL does eventually go away completely
to be replaced by a much lower level representation (at the moment
I can't remember what it's called). This is done before they do
register allocation and scheduling, IIRC.
