We would only increment write barrier counters from the the MacroAssembler's
RecordWrite method which is only used in limited cases. Instead, we should
increment it inside the RecordWrite stub, this way we catch all uses, including
WASM.
Also, we had a static counter aimed at telling us how many barriers exist in
generated code, as opposed to how many are executed. This counter was not
functional since the compiler isn't aware of counters at the moment. Let's just
remove it to avoid confusion.
