    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.

    gcc/
            PR sanitizer/97696
            * asan.cc (asan_expand_mark_ifn): Allow the length to be a
poly_int.

    gcc/testsuite/
            PR sanitizer/97696
            * gcc.target/aarch64/sve/pr97696.c: New test.

    (cherry picked from commit fca6f6fddb22b8665e840f455a7d0318d4575227)=
