    asan: Handle poly-int sizes in ASAN_MARK [PR97696]

    This patch makes the expansion of IFN_ASAN_MARK let through
    poly-int-sized objects.  The expansion itself was already generic
    enough, but the tests for the fast path were too strict.

            * asan.cc (asan_expand_mark_ifn): Allow the length to be a
poly_int.
