How to implement:

boolean changesOnly(T fieldOrGetter);

analyse stack, require last call being invoke* or getfield
for getfield, make sure it's a non-static field of the target class, set all other fields on unchangeable
for invoke*, make sure it's a non-static method of the target class returning a value, instrument assuming the last getfield is the one we want
