This PR makes `#guard_msgs` to treat `trace` messages separate from `info`, `warning` and `error`. It also introduce the ability to say `#guard_msgs (pass info`, like `(drop info)` so far, and also adds `(check info)` as the explicit form of `(info)`, for completeness. Fixes #8266

This is a test for a `simp` cache issue where the following incorrect goal was being
|
|
produced.
|
|
```
|
|
... |- id (2*x + y) = id (x + x)
|
|
```
|
|
instead of
|
|
```

... |- id (2*x + y) = id (2*x)
