Union field address taken with `--take-no-union-field-addr`

[KRM7]

Csmith will sometimes still generate programs which take the address of a union field, even when the --take-no-union-field-addr option is used:

/*
 * This is a RANDOMLY GENERATED PROGRAM.
 *
 * Generator: csmith 2.4.0
 * Git version: 0ec6f1b
 * Options:   --max-array-dim 5 --max-array-len-per-dim 20 --no-longlong --no-packed-struct --take-no-union-field-addr
 * Seed:      1438579922
 */

The program generated with the above options will use the address of a union field in several places.
