- The k-th parameter (k > 1) has offset equal to the
sum of:
- the offset of the k-1-st paramter
- - the int-promoted size of the k-1-st parameter.
+ - the (void *)-promoted size of the k-1-st parameter.
Note that the encoded offsets need not correspond
to the actual placement of parameters (relative to 'self')
