   misalignment by INCREMENT modulo its current alignment.

bool get_ptr_info_alignment	(	struct ptr_info_def *	pi,

   If the alignment of the pointer described by PI is known, return true and
   store the alignment and the deviation from it into *ALIGNP and *MISALIGNP
   respectively.  Otherwise return false.
