Make opt_aref instruction support Integer#[]

only when its receiver and the argument are both Integers.

Since 6bedbf4625, Integer#[] has supported a range extraction.
This means that Integer#[] now accepts multiple arguments, which made
the method very slow unfortunately.

This change fixes the performance issue by adding a special handling for
its traditional use case: `num[idx]` where both `num` and `idx` are
Integers.
