Fix length checking for Unicode identifiers containing escapes (U&"...").
We used the length of the input string, not the de-escaped string, as
the trigger for NAMEDATALEN truncation. AFAICS this would only result
in sometimes printing a phony truncation warning; but it's just luck
that there was no worse problem, since we were violating the API spec
for truncate_identifier(). Per bug #9204 from Joshua Yanovski.
This has been wrong since the Unicode-identifier support was added,
so back-patch to all supported branches.
