Codegen for the raw/struct buffer access intrinsics would update the offset in the MMO to reflect the combined offset, if it was known to be constant. If the combined offset was not known to be constant, or if there was an index, it would set the offset in the MMO to 0. This is unsafe because it makes it look like the access does not alias with another access with a fixed non-zero offset. Fix these cases by setting the pointer in the MMO to null, to reflect the fact that we do not have any known IR value pointer + constant offset for the access.
