Optimize (SETF SCHAR).
The transform on HAIRY-DATA-VECTOR-SET transformed the NIL case into
DATA-VECTOR-SET which then derived the type of VALUE to be NIL, which
conflicts with any other type at compile-time and the data-vector-set
VOP has no chance of being invoked.
Transform into NIL-ARRAY-ACCESSED-ERROR directly.
