bpo-37758: Extend unicodedata checksum tests to cover all of Unicode.

gnprice · gnprice · commit 517484c43f1f · 2019-09-11T20:38:19.000-07:00
Unicode has grown since Python first gained support for it, when Unicode itself was still rather new. This pair of test cases was added in commit 6a20ee7 back in 2000, and they haven't needed to change much since then. But do change them to look beyond the Basic Multilingual Plane (range(0x10000)) and cover all 17 planes of Unicode's final form. This adds about 5 seconds to the test suite's runtime. Mark the tests as CPU-using accordingly.
