  @param indexes current positions of the instructions to be resized. Each
  instruction must be designated by the index of its <i>last</i>
  byte, plus one (or, in other words, by the index of the <i>first</i>
  byte of the <i>next</i> instruction).
  @param sizes the number of bytes to be <i>added</i> to the above
  instructions. More precisely, for each i < <tt>len</tt>,
  <tt>sizes</tt>[i] bytes will be added at the end of the
  instruction designated by <tt>indexes</tt>[i] or, if
  <tt>sizes</tt>[i] is negative, the <i>last</i> |<tt>sizes[i]</tt>|
  bytes of the instruction will be removed (the instruction size
  <i>must not</i> become negative or null).
  @param label the label whose offset must be updated.
