@rampitec I don't think there is a way to pass the ORE->emit argument lambda
expression into the reportAtomicExpand() function because of its capture. It
needs access to RMW from the enclosing scope. (Well, I could define a copy of
RMW and somehow pass it into the lambda but that seems too much for this task)
