Issue #3742 Changing the axesSizeProduct entries to Integer.MAX_VALUE instead of throwing exception

[HelenaGregg]

#3742 said that they would like to be able to create a Sets::cartesianProduct object that would have more than 2^31-1 elements in the resulting set. Currently, it throws an IllegalArgumentException when this happens. @Meijuh said that since "java.util.Set::size() specifies that if the size would be more than Integer.MAX_VALUE it would simply be Integer.MAX_VALUE" this should be fixed.
So the code change is that instead of throwing an exception, the remaining lower parts of the axesSizeProduct integer array are set to Integer.MAX_VALUE so the size function (which returns axesSizeProduct[0]) will now return Integer.MAX_VALUE.

Several other methods are defined in terms of axesSizeProduct and make assumptions about how it works, so please add tests for them; I suspect that several of them are broken in the current version.
In particular, iterator and contains. (Further thinking about this brought up #3873 and #3874 .)

In particular:

• I'm not sure List.indexOf is well-defined for a list of size greater than Integer.MAX_VALUE, so we'd have to make a decision what to do there. I prefer throwing IndexOutOfBoundsException, if only because Objects.equal(list.get(list.indexOf(o)), o) should always be true if index is not -1, and list.indexOf(o) >= 0 should be as equivalent as possible to list.contains(o). (Note that this change also affects Lists.cartesianProduct, so indexOf is a method that needs to be supported.
• The iterator needs to return the next element after you've called next Integer.MAX_VALUE times. Unfortunately, I'm not sure that can be tested without being very slow, and I don't know how to solve that.
• contains definitely needs to be tested, including on elements whose "index" would be greater than Integer.MAX_VALUE. That probably means it needs a new implementation separate from indexOf, which would ideally also address Sets.cartesianProduct.contains' complexity depended on now-removed optimization in Android version #3873.
