Confirmed, but I don't see it happening at the RTL level either in 3.5.0, so
I'll remove the TREE keyword.
The optimization did happen with 2.95.3 though. I'll mark it as a regression,
even if I expect only a tree-level solution to happen (maybe already with
GCSE), so it won't probably be fixed for the 3.3 branch or 3.4 branch.
