    cselib: Skip BImode while keeping track of subvalue relations [PR107088]

    For BImode get_narrowest_mode evaluates to QImode but BImode < QImode.
    Thus FOR_EACH_MODE_UNTIL never reaches BImode and iterates until OImode
    for which no wider mode exists so we end up with VOIDmode and fail.
    Fixed by adding a size guard so we effectively skip BImode.

    gcc/ChangeLog:

            * cselib.cc (new_cselib_val): Skip BImode while keeping track of
            subvalue relations.
