We currently produce a single table for all categories of code point
properties (GeneralCategory, Script, etc.). Each row contains a field
indicating the range of code points to which that property applies. At
runtime, we then do a binary search through that table to decide if a
code point has a property.
This changes our approach to generate a 2-stage lookup table for each of
those categories. There is an in-depth explanation of these tables above
the new `create_code_point_tables` method. The end effect is that code
point property lookup is reduced from a binary search to constant-time
array lookups.
In total, this change:
* Increases the size of libunicode.so from 2.7 MB to 2.9 MB.
* Reduces the runtime of the new benchmark test case added here from
3.576s to 1.020s (a 3.5x speedup).
* In a profile of resizing a TextEditor window with a 3MB file open,
the runtime of checking if a code point has a word break property
reduces from ~81% to ~56%.
