I can tackle it in a separate patch.
For mode 2 and 3 calls, we can annotate the calls with something that indicates
whether they can be merged only with other calls if the reason is the same or
they cannot be merged at all. For calls in mode 3, we can just annotate the
calls with attribute `nomerge`. For mode 2, I think we need to annotate the
calls with an attribute or something that distinguishes the calls from the
calls that are mergeable (mode 1) and the ones that aren't (mode 3).
