[sil-aa] AA::may{Read,Write,ReadOrWrite}FromMemory do not care about ref counts. Add a flag to ignore ref counts during such a query.
...
This is due to MayHaveSideEffects encompassing ref count effects and a
myriad of other effects. If/when we separate the two concepts (which is
cleaner IMHO), the flag will no longer be necessary.
