int check in checked mode is problematic

[peter-ahe-google]

Our int check in checked mode doesn't work for integers outside the 32bit range.

[peter-ahe-google]

The new fixnum library is failing a unit test in checked mode. The problem is code like this:

int x = 2147483648;

It's actually even worse than not working for integers outside the 32-bit range. All our bitwise operations produce unsigned 32-bit results and our int type checks fail for unsigned integers outside the 31-bit range. The reason is that we use code like this to check for it:

   if (i !== (i | 0)) ...

and i | 0 forces a conversion to a signed 32-bit integer.
