Folds over the substructure of a type, visiting its component types and all regions that occur free within it.
That is, Ty can contain function or method types that bind
regions at the call site (ReLateBound), and occurrences of
regions (aka "lifetimes") that are bound within a type are not
visited by this folder; only regions that occur free will be
visited by fld_r.
