Andrey Konovalov f1e8564c55 FROMLIST: kasan, scs: support tagged vmalloc mappings 
Fix up the custom KASAN instrumentation for Shadow Call Stack to support
vmalloc() mappings and pointers being tagged.

- Use the tagged pointer returned by kasan_unpoison_vmalloc() in
  __scs_alloc() when calling memset() to avoid false-positives.

- Do not return a tagged Shadow Call Stack pointer from __scs_alloc(),
  as this might lead to conflicts with the instrumentation.
