Refactor \X regex handling to avoid a typical case table lookup
Prior to this commit 98.4% of Unicode code points that went through \X
had to be looked up to see if they begin a grapheme cluster; then looked
up again to find that they didn't require special handling. This commit
refactors things so only one look-up is required for those 98.4%. It
changes the table generated by mktables to accomplish this, and hence
the name of it, and references to it are changed to correspond.
