Actually, if I recall correctly, there isn't an implicit cast either
way for the case of array subscripting.

The issue with inserting an implicit cast from long long to int is
that conceptually, it isn't there!  The fact that we truncate long
long to i32 in CodeGen is really just an artifact of the
implementation on 32-bit machines.
