Seems reasonable and do-able except it gets kinda messy:

 1. Allocation type mismatch doesn't exist for HWASan and it would mean therefore forking that test into two files anyway.
 2. There aren't sanitizer_common tests in gn, only check-hwasan/check-asan, and hwasan tests are most important and easiest to invoke for android through gn.
