Remove relics of regex swash use
This removes the most obvious and easy things that are no longer needed
since regexes no longer use swashes at all.
tr/// continues, for the time being, to use swashes, so not all swash
handling is removable now. But tr/// doesn't use inversion lists, and
so a bunch of code is ripped out here. Other code could have been, but
I did only the relatively easy stuff. The rest can be ripped out all at
once when tr/// is stops using swashes.
