Summary:
Array types where the length is not statically known were represented
using fresh variables. This diff:
- Makes array type length optional, reducing the amount of work needed
for renaming, substitution, and normalization.
- Revises uses of array length so that the length component of a
Tarray type represents only the statically determined constant
length of an array type, and the length component of a Sizeof
expression represents the dynamically determined length of an array
value.
- Restricts the type of static lengths from a general expression
(Sil.exp) to an integer (Sil.Int.t), enforcing that static types are
constant. This in particular ensures that types contain no
variables, and so are invariant under operations such as renaming
and substitution.
- Removes the type substitution and renaming functions typ_sub,
typ_normalize, and typ_captured_ren. Now that array type lengths
are constant integers, all of these functions are the identity.

This diff extends Sizeof expressions with an optional expression for the

simple array `sizeof(t[n])` is represented by (modulo subtyping info)
`Sizeof t (Some n)`, and sizeof a struct whose final member is an array
`sizeof(struct s {... t[n] f})` is represented by `Sizeof (struct s
{... t[n] f}) (Some n)`.
This is an intermediate step toward eliminating expressions from types,
the redundancy between the length in the types and in the sizeof
expressions will be eliminated later.
