    pointer-compare-1.c: Add __attribute__((used))

    c-c++-common/asan/pointer-compare-1.c assumes the certain order for
    variable placement.  Add __attribute__((used)) to avoid variable
    placement changes due to SHF_GNU_RETAIN.

            PR testsuite/97803
            * c-c++-common/asan/pointer-compare-1.c (global1): Add
            __attribute__((used))
            (global2): Likewise.
            (small_global): Likewise.
            (large_global): Likewise.=
