Mitch Phillips	5f2a74c87a	[GWP-ASan] Update alignment on Android. Summary: Android has different alignment requirements. You can read more about them here (https://cs.android.com/android/platform/superproject/+/master:bionic/tests/malloc_test.cpp;l=808), but the general gist is that for malloc(x <= 8), we do malloc(8), and for everything else, we do 16-byte alignment.

This class contains the logic for creating and maintaining allocations in the guarded pool. Its public interface is to be utilised by supporting allocators in order to provide sampled guarded allocation behaviour. This patch also contains basic functionality tests of the allocator as unittests. The error-catching behaviour will be tested in upcoming patches that use Scudo as an implementing allocator.
