Autogenerate yarr character tables
https://bugs.webkit.org/show_bug.cgi?id=37877

Use a python script to automatically generate character tables
for the builtin YARR character classes. This allows us to generate
actual tables as well, by using these tables we can both increase
performance of the check (for complex builtins) and reduce the actual
code size.

4-8% win on string-unpack-code, but lots of noise on other tests so
i'm only confident saying its a 1% win overall.
