Remove deprecated doFormat

[wilzbach]

Apparently we missed the deprecation cleanup on this one.

It's part of undeaD:

LGTM

Looks like a test in DMD still uses doFormat:

What's up with the CI failure?

What's up with the CI failure?

This has to do with the new public unittest tester: to avoid random failures a specific git version of the tools repo is checked out.
The problem is that we do a git clone with --depth 1 by default and just recently a new commit got into the tools repo, s.t. the checked out version isn't fetched anymore due.

-> #4955

The CircleCi fix is in & now it's green again :)
