13bda0e 
…r deadcode-only changes

We're guaranteed we won't infinite loop on deadcode-only changes,
because each change converts valid -> invalid, and there are only a
finite number of valid values.

The loops this test is looking for are those generated by rule
applications, so it isn't useful to check for loops when rules aren't
involved.

Fixes #52366
