    diagnostics: Make line-ending logic consistent with libcpp [PR91733]

    libcpp recognizes a lone \r as a valid line ending, so the infrastructu=
re
    for retrieving source lines to be output in diagnostics needs to do the
    same. This patch fixes file_cache_slot::get_next_line() accordingly so =
that
    diagnostics display the correct part of the source when \r line endings=
 are
in
    use.

    gcc/ChangeLog:

            PR preprocessor/91733
            * input.cc (find_end_of_line): New helper function.
            (file_cache_slot::get_next_line): Recognize \r as a line ending.
            * diagnostic-show-locus.cc (test_escaping_bytes_1): Adapt selft=
est
            since \r will now be interpreted as a line-ending.
