HWASan support in ART.
Two small tweaks:
* The highest 8 bits of a pointer in hwasan contain a random tag which needs to
be removed before comparing _unrelated_ pointers.
* Annotate DoLongJump. HWASan needs to re-tag the newly unallocated stack space
to match SP. This is similar to ASan annotation (__asan_handle_noreturn), but
more precise - HWASan needs to know the destination SP address because it can
not conservatively "unpoison" the entire stack like ASan does.

Test: mmm SANITIZE_TARGET=hwaddress
