Issue #789290: make sure that hash(2**63) == hash(2.**63) on 64-bit platforms. The previous code was fragile, depending on the twin accidents that: (1) in C, casting the double value 2.**63 to long returns the integer value -2**63, and (2) in Python, hash(-2**63) == hash(2**63). There's already a test for this in test_hash.
