Takes two non-negative integer numbers separated by a comma.

Prepend the function label with the number of two-byte Nop

instructions indicated by the first. Append Nop instructions

(six, four or two bytes), beginning with the largest possible
|
|
size. Using 0 for both values disables hotpatching.
