commit 77a6d8568e288ad300ad7f0805946559b4ec28d1

regexec.c: Less work in /i matching
If you watch an execution trace of regexec /i, often you will see it
folding the same thing over and over, as it backtracks or searches
ahead. regcomp.c has now been changed to always fold UTF-8 encoded
EXACTF and EXCACTFU nodes. This allows these to not be re-folded each
time.
This commit does it just for find_by_class(). Other commits will expand
this technique for other cases.
