  [LV] Add test case for diff checks with nested AddRecs.

Add a test case where the AddRec for the pointers in the inner loop
have the AddRec of the outer loop as start value.

It is sufficient to subtract the start values (%dst, %src) of the outer
AddRecs. This simplification will be done in a follow-up commit.
