That's what we should phase out. The eventual aim should be for (a)
folding on GIMPLE (gimple-fold etc. - working with SSA not combined trees)
as an optimization and (b) folding done by front ends only when required
for language semantics (e.g. constant expressions). If you want to
optimize type sizes, look at where they are located in the GIMPLE IR, as a
property of the IR rather than as a hook checking global state.
