Use a static exception map
* Make the map static, read-only and preinitialized, to avoid
thread-safety problems.
* Invert the map, making it non-zero for exceptional characters
(so that non-exceptional characters don't need to be mentioned)
* Tighten the set of exceptional characters, so that most of ASCII
goes through the fast path.
This increases the speed of test_perf_* by 7.7-20.6%.
