    tree-optimization/103759: Use sizetype everywhere for object sizes

    Since all computations in tree-object-size are now done in sizetype and
    not HOST_WIDE_INT, comparisons with HOST_WIDE_INT based unknown and
    initval would be incorrect.  Instead, use the sizetype trees directly to
    generate and evaluate initval and unknown size values.

    gcc/ChangeLog:

            PR tree-optimization/103759
            * tree-object-size.c (unknown, initval): Remove functions.
            (size_unknown, size_initval, size_unknown_p): Operate directly
            on trees.
