See if I
should be considered for address type promotion.
We check if I
is a sext with right type and used in memory accesses. If it used in a "complex" getelementptr, we allow it to be promoted without finding other sext instructions that sign extended the same initial value. A getelementptr is considered as "complex" if it has more than 2 operands.
