New transformation roughly parallels the old constant-folding code + dead-code-elimination (eliminating cases from conditionals/tail-loops and transforming into DFGs, left for another PR). Should be significantly more powerful, and flexible - e.g. the old code broke if OpType::const_fold returned only some outputs from a leaf op.

All the existing constant-folding tests pass! 😀 🚀, plus at least one that didn't just fail-to-optimize, but panicked - or, in release mode, potentially produced an invalid hugr - see comment.

closes #1322

BREAKING CHANGE: ConstantFoldPass is no longer UnwindSafe.
BREAKING CHANGE: ConstantFoldPass is no longer RefUnwindSafe.
BREAKING CHANGE: ConstantFoldPass no longer derives Copy.
BREAKING CHANGE: fold_leaf_op function removed.
BREAKING CHANGE: find_consts function removed.
BREAKING CHANGE: ConstantFoldPass::new function removed. Instead use ConstantFoldPass::default.
BREAKING CHANGE: Variant ConstFoldError::SimpleReplacementError was removed.

Is it worth keeping the ValueOrSum intermediate??

// Unfortunately we need From<ValueHandle> for Value to be able to pass
// Value's into interpret_leaf_op. So that probably doesn't make sense...

I don't quite follow. What doesn't make sense?. Why do we need From for Value?.

I don't like the single_linked_output().unwrap(), but it's not so bad. I've created #1750


if h.get_optype(n).is_cfg() {
for bb in h.children(n) {
//if results.bb_reachable(bb).unwrap() { // no, we'd need to patch up predicates

but i don't really understand the argument here -- wouldn't the commented code be better?

I don't follow either. I would prefer to leave it in, Alan can explain to us when he's back.
