Same comment wrt inline functions applies.
Here, because there's one result, writing to byte 7, I wonder if it isn't
clearer to write the loop
first_equal = n;
Implement it similar to VECTOR FIND ANY ELEMENT EQUAL.
The zero-check seems to have precedence in case we have
"data1 == data2 == 0". The description in the PoP is a little bi
confusing.
