patch 8.2.3573: cannot decide whether to skip test that fails with 64 bit

Browse Source 
Problem:    Cannot decide whether to skip test that fails with 64 bit ints.
            (closes #9072)
Solution:   Add v:sizeofint, v:sizeoflong and v:sizeofpointer.  Improve the
            check for multiply overflow.
