So, in general you need to ensure that the new forms of trees are 
TREE_CONSTANT and pass initializer_constant_valid_p.  If not 
TREE_CONSTANT, look at where they are built up and find where 
TREE_CONSTANT is lost.  If failing initializer_constant_valid_p, work out 
how to adapt that function to cover the new canonical forms of trees.
