  * ALIGNED_POINTER is a boolean macro that checks whether an address

  * (within reasonable limits).
  *
  * armv4 and v5 require alignment to the type's size.  armv6 requires 8-byte
  * alignment for the ldrd/strd instructions, but otherwise follows armv7 rules.
  * armv7 requires that an 8-byte type be aligned to at least a 4-byte boundary;
  * access to smaller types can be unaligned, except that the compiler may
  * optimize access to adjacent uint32_t values into a single load/store-multiple
  * instruction which requires 4-byte alignment, so we must provide the most-
  * pessimistic answer possible even on armv7.
