The following spec is accepted by the typechecker even though it makes no sense (there is no prestate when the constructor is running):

constructor of C
interface constructor()

iff

    x == 7

creates

    uint x := 2

We should modify the typechecker to reject specs containing storage references in constructor precondition blocks.
