Yea, I almost built one. That's easy enough to add.
2) you might end up with redundant work(?) as you are iterating

I think it is quite obviously a good idea and might make regression

As discussed in the BZ, we have multiple problems with how we sort the
coalesce list during out-of-ssa coalescing.
First, the sort is not stable. If the cost of two coalesce pairs is the
same, we break the tie by looking at the underlying SSA_NAME_VERSION of
the first, then the second eleme
