I have a problem with this patch.

It makes: perf mem -t store rec record OP_NA for the store.
It was recording OP_STORE before.

I think we need to keep LD/ST info. This is useful for analysis
especially if we collect loads/stores simultaneously.

Was working before for the mem-loads, mem-stores events.
