I like the idea of reducing the number of tree codes we use in optimizers.  
Do you plan to do these simplifications during the gimplification?
If so, you have to generate code (gotos and labels) for the tree_cfg_builder.
The other solution is to use the CFG for these transformations, and in a first 
time generate the corresponding trees for a CFG transformation.
