GWP-ASan is part of the native allocator, and may allocate some memory.
When GWP-ASan is enabled, the malloc tests need to look inside of
GWP-ASan regions as well for native allocations.

This avoids issues where an allocation could create a map while trying
to check data from the maps and running malloc_iterate.

* HWASan report invalid use of the allocator api (like alignment not
being power of two, or allocation size too large) in a way tests do not
expect.
* Code in .preinit_array runs before HWASan shadow is initialized and
needs to be excluded from instrumentation.
* It looks that mm system calls (mmap/mprotect/etc) will not allow
tagged pointers. In fact, the use of mprotect on malloc()ed memory is
doubtful - one can imagine some kind of speculative load from such
memory, as compiler knows that it is addressable.
