## Message

```
more optimized and correct management of 8-bit PC counters

* Upgrade from u8 to usize element types.
  - WebAssembly assumes u64. It should probably try to be target-aware
    instead.
* Move the covered PC bits to after the header so it goes on the same
  page with the other rapidly changing memory (the header stats).

depends on the semantics of accepted proposal #19755

closes #20994

```
