Combine this and another taint vector to represent a tainted indirect read

<p>
Because the all bytes of the address offset "affect" the value read, we first union all the
taint sets of the that offset. We then tag each mark in that union with "{@code indR}".
Finally we union that result with each element of this vector (this vector representing the
bytes read from memory).

@param offset the vector representing the bytes that encode the offset
@return the vector representing the tainted bytes read from memory
