PR c/68187: fix overzealous -Wmisleading-indentation (comment #0)

gcc/c-family/ChangeLog:
        PR c/68187
        * c-indentation.c (should_warn_for_misleading_indentation): When
        suppressing warnings about cases where the guard and body are on
        the same column, only use the first non-whitespace column in place
        of the guard token column when dealing with "else" clauses.
        When rejecting aligned BODY and NEXT, loosen the requirement
        from equality with the first non-whitespace of guard to simply
        that they not be indented relative to it.

gcc/testsuite/ChangeLog:
        PR c/68187
        * c-c++-common/Wmisleading-indentation.c (fn_40_a): New test
        function.
        (fn_40_b): Likewise.
        (fn_41_a): Likewise.
        (fn_41_b): Likewise.
