    tree-optimization/104970: Limit size computation for access attribute

    Limit object size computation only to the simple case where access
    attribute has been explicitly specified.  The object passed to
    __builtin_dynamic_object_size could either be a pointer or a VLA whose
    size has been described using access attribute.

    Further, return a valid size only if the object is a void * pointer or
    points to (or is a VLA of) a type that has a constant size.

    gcc/ChangeLog:

            PR tree-optimization/104970
            * tree-object-size.cc (parm_object_size): Restrict size
            computation scenarios to explicit access attributes.

    gcc/testsuite/ChangeLog:

            PR tree-optimization/104970
            * gcc.dg/builtin-dynamic-object-size-0.c (test_parmsz_simple2,
            test_parmsz_simple3, test_parmsz_extern, test_parmsz_internal,
            test_parmsz_internal2, test_parmsz_internal3): New tests.
            (main): Use them.
