    tree-optimization/104942: Retain sizetype conversions till the end

    Retain the sizetype alloc_object_size to guarantee the assertion in
    size_for_offset and to avoid adding a conversion there.  nop conversions
    are eliminated at the end anyway in dynamic object size computation.

    gcc/ChangeLog:

            PR tree-optimization/104942
            * tree-object-size.cc (alloc_object_size): Remove STRIP_NOPS.

    gcc/testsuite/ChangeLog:

            PR tree-optimization/104942
            * gcc.dg/builtin-dynamic-object-size-0.c (alloc_func_long,
            test_builtin_malloc_long): New functions.
            (main): Use it.
