Diff from mypy_primer, showing the effect of this PR on open source code: spack (https://github.com/spack/spack): typechecking got 1.26x slower (56.1s -> 70.7s)
(Performance measurements are based on a single noisy sample)

Fixes #16427 The test case added in the first commit crashes. The second commit addresses the crash - I don't know whether this fix is correct, it just happens to stop the crash but it leads to a code branch which just `continue`s out of a for loop iteration, so it might be bypassing something it shouldn't. I don't completely understand it. --------- Co-authored-by: Ivan Levkivskyi <levkivskyi@gmail.com>
