Currently CheckedInt<int>, CheckedInt<long long> works, but not CheckedInt<long>.

>From compiling error, seems like the code was confused on what's the next level of integer above long.

That should be platform dependent.  If long is 32bit, then the next level should be long long.  If long is 64 bit, then the  next level should be undefined.

Fixing this could simply be a check of the sizeof(long) and map it either to int or long long.

Once this is fixed, we should use GC3D types when using CheckedInt instead of int32_t and uint32_t we currently use.
