Hmm. Given that the only user-visible feature here is better support
for -Wuninitialized, I think we're probably better served by delaying
this until gcc 3.2 when we ought to have actual optimizations to go
with it.
The main infrastructure change I'd like to see in gcc 3.2 is to have
all front ends do functions-as-trees, and remove the old rtl inliner.
