Use macro not swash for utf8 quotemeta
The rules for matching whether an above-Latin1 code point are now saved in a macro generated from a trie by regen/regcharclass.pl, and these are now used by pp.c to test these cases. This allows removal of a wrapper subroutine, and also there is no need for dynamic loading at run-time into a swash. This macro is about as big as I'm comfortable compiling in, but it saves the building of a hash that can grow over time, and removes a subroutine and interpreter variables. Indeed, performance benchmarks show that it is about the same speed as a hash, but it does not require having to load the rules in from disk the first time it is used.
