[perl #56444] delayed interpolation of \N{...} charnames escapes in regexes in perl 5.9.x and later causes breakage - they should be resolved and then converted to \x{...} not preserved verbatim

Adding just for the record:

Some of the problems here turn out to be flaws in the charnames handler that were later fixed; but there still would be problems when a regex gets interpolated into another regex outside the original scope, so something like what is done here is required.
