    tree-object-size: Don't let error_mark_node escape for ADDR_EXPR [PR105736]

    The addr_expr computation does not check for error_mark_node before
    returning the size expression.  This used to work in the constant case
    because the conversion to uhwi would end up causing it to return
    size_unknown, but that won't work for the dynamic case.

    Modify the control flow to explicitly return size_unknown if the offset
    computation returns an error_mark_node.

    gcc/ChangeLog:

            PR tree-optimization/105736
            * tree-object-size.cc (addr_object_size): Return size_unknown
            when object offset computation returns an error.

    gcc/testsuite/ChangeLog:

            PR tree-optimization/105736
            * gcc.dg/builtin-dynamic-object-size-0.c (TV4): New struct.
            (val3): New variable.
            (test_pr105736): New test.
            (main): Call it.
