Member predicate PaddedType :: optimalSize
Gets the optimal size of this type on architecture arch, that is,
the sum of the sizes of all fields, ignoring padding
between them, but adding any trailing padding required to align
the type properly. This is a lower bound on the actual size that
can be achieved just by reordering fields, and without
reorganizing member structs’ field layouts.
