For -L0_filter on drcachesim, storing only the PC and data address is not enough to figure out during post-processing which memref it was for a multi-memref instruction. Here we add a new offline entry type to store the memref type and size and use it for multi-memref instructions where the memrefs are different (when identical, such as for ALU operations, the first will pass the filter and be picked in post-processing).
