I am not sure how that would work: provided that getTypeSize() returns the size
of the struct, which will match any alignment of the element, we need the size
value to get the right type for the element, and the SingleElementTy to know
that it is actually an fp type.
Maybe the switch could be simplified a bit by checking first that the
SingleElementTy is one of these three types, and then return the type based on
the size only?
