Log Message:
- Make ALIGNED_POINTER use __alignof(t) instead of sizeof(t). This is more
  correct because it works with non-primitive types and provides the ABI
  alignment for the type the compiler will use.
- Remove all the *_HDR_ALIGNMENT macros and asserts
- Replace POINTER_ALIGNED_P with ACCESSIBLE_POINTER which is identical to
  ALIGNED_POINTER, but returns that the pointer is always aligned if the
  CPU supports unaligned accesses.
