Well, I disagree.  STATEMENT_LISTs are just another kind of thing you 
encounter in an expression; if a caller wants special handling, they can 
arrange for it.

This is how things used to work before, but it broke when the tree-ssa 
merge switched from using TREE_CHAIN on statements to a separate 
STATEMENT_LIST.
