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)
