After r14-1655-g52c92fb3f40050 (and the other commits
which touch zero_one_valued_p), we end up with a with
`bool * a` but where the bool is an SSA name that might not
have non-zero bits set on it (to 0x1) even though it
does the non-zero bits would be 0x1.
The case of coremarks, it is only phiopt4
