Same with the freebsd build bot

Hm. It looks like it isn't actually rebuilding it every build, but the build directories get wiped out whenever the bots restart.

Use the better FnEntry spans in protector errors

Example error, from `tests/fail/stacked_borrows/invalidate_against_protector1.rs`:
```
error: Undefined Behavior: not granting access to tag <3095> because that would remove [Unique for <3099>] which is protected because it is an argument of call 943
  --> tests/fail/stacked_borrows/invalidate_against_protector1.rs:5:25

   = help: this indicates a potential bug in the program: it performed an invalid operation, but the Stacked Borrows rules it violated are still experimental
