Honest question is it worth testing this if nothing is using it what is the
point?

I don't feel strongly about this; I'm happy to just remove the ifdef'd tests,
because it's really annoying to read all the conditionals.

+#if !defined(ARCH_CPU_ARM_FAMILY) || defined(__clang__)
   static LazyInstance<AlignedData<4096> > align4096 = LAZY_INSTANCE_INITIALIZER;

   EXPECT_ALIGNED(align4.Pointer(), 4);
   EXPECT_ALIGNED(align32.Pointer(), 32);

   EXPECT_ALIGNED(align4096.Pointer(), 4096);
