Add 256 word bit table of character classes
This patch adds a table for looking up character classes. It is 256
words long, in l1_char_class_tab.h, with each word corresponding to the
ordinal of a Latin1 character, and each word contains a bit map of all
the properties that character matches. Each property has a bit or two.
Ones named _CC_property_A are true only if the character is also in the
ASCII character set. Ones named CC_property_L1 do not have this
restriction. (L1 stands for Latin1.)
Also added is a script that generates the table. It is not anticipated
that this will need to be used often.
(This commit was changed from its original form by Steffen.)
