Neither of these look like a good name to me, OEP_IGNORE_MEMBER_OFFSET
seems like a request that member offset is not important to the equality,
it is always important, but in the new mode we want not just the member
offset to be equal, but also the fields to be the same, i.e. a stronger
requirement.
So, what about
/* For OEP_ADDRESS_OF of COMPONENT_REFs, only consider same fields as
equivalent rather than also different fields with the same offset. */
OEP_ADDRESS_OF_SAME_FIELD = 256
