    preprocessor: Fix column adjustment [PR 99446]

    This ICE was because when adjusting a column offset we could advance
    into a linemap for a different file.  We only checked the next line
    map was not for a line further advanced in any file, forgetting that
    it could be for an earlier line in a different file.  The testcase
    needed adjusting as column 512 was unrepresentable, once that was
    taken into consideration.
