regexp.t: Add 'no warnings "utf8";
This .t works fine unless there are failures that it tries to output,
and the handle hasn't been opened using utf8. Because we aren't sure if
that operation works, just turn off warnings.

utf8.h: Correct some values for EBCDIC
It occurred to me that EBCDIC has different maximums for the number of
bytes a character can occupy. This moves the definition in utf8.h to
within an #ifndef EBCDIC, and adds the correct values to utfebcdic.h

regex: White-space, comment only; no code changes
This outdents code that just had its containing block removed, and
reflows its comments to fill 79 columns; and does some other white space
adjustments, plus a typo in a comment.

regex: Splice out no longer used array element
A recent commit removed all uses of an array element in the middle of an
array. This moves up the elements that followed it.

regex: Remove old code that tried to handle multi-char folds
A recent commit has changed the algorithm used to handle multi-character
folding in bracketed character classes. The old code is no longer
needed.

PATCH: [perl #89774] multi-char fold + its fold in char class
The design for handling characters that fold to multiple characters when
the former are encountered in a bracketed character class is defective.
The ticket reads, "If a bracketed character class includes a character
that has a multi-char fold, and it also includes the first character of
that fold, the multi-char fold will never be matched; just the first
character of the fold.". Thus, in the class /[\0-\xff]/i, \xDF will
never be matched, because its fold is 'ss', the first character of
which, 's', is also in the class.
The reason the design is defective is that it doesn't allow for
backtracking and trying the other options.
This commit solves this by effectively rewriting the above to be
/ (?: \xdf | [\0-\xde\xe0-\xff] ) /xi. And so the backtracking gets
handled automatcially by the regex engine.

regcomp.c: Rename a macro, fix-up comments
This very recently introduced macro's name could be clearer, and it can
be used in another place, and the comment concerning that is slightly
inaccurate.
