   We initially store MY_PLT_INDEX in the high bits so that we can use the all
   16 bits as an unsigned offset; if we use the low bits we would get an
   unwanted sign extension.  The PLT header then rotates the index to get the
   right value, before calling the resolution routine.  This computation can
   fit in unused bundle slots so it's free.

   This code sequence lets the code at at the start of the PLT determine
   which PLT entry was executed by examining 'r29'.

   Note that MY_PLT_INDEX skips over the header entries, so the first
   actual jump table entry has index zero.
