## Message

```
Make invalidFmtError public and use in place of compileErrors for bad format strings (#13526)

* Export invalidFmtErr

To allow consistent use of "invalid format string" compile error
response for badly formatted format strings.

See https://github.com/ziglang/zig/pull/13489#issuecomment-1311759340.

* Replace format compile errors with invalidFmtErr

- Provides more consistent compile errors.
- Gives user info about the type of the badly formated value.

* Rename invalidFmtErr as invalidFmtError

For consistency. Zig seems to use “Error” more often than “Err”.

* std: add invalid format string checks to remaining custom formatters

* pass reference-trace to comp when building build file; fix checkobjectstep
```
