XXX EBCDIC header files
XXX See if changing \xE2 to \xE1 causes lex.t to work for EBCDIC

\xE2 is 'S' in EBCDIC, and so is going to be legal.  \xE1 is not an
ASCII equivalent.
Added Porting/reorder_charclass_invlists.pl

This program is used too bootstrap perl onto a non-ASCII platform with
no pre-existing perl.
t/TEST: Don't bail if fails in t/base
hv.c: Stop being ASCII-centric

This uses macros which work cross-platform.  This has the added advantge
that it is much clearer what is going on.
dump.c: Make less ASCII-centric:

This has the added advantage of being clearer as to what is going on.
lib/charnames.t: Make some tests work under EBCDIC
sv.c: Make less ASCII-centric
Data-Dumper: Make EBCDIC-friendly
APItest/t/handy.t: Make EBCDIC-friendly
genpacksizetables.pl: Correct comment typo
toke.c: Simplify some code

We don't have to test separately for lower vs uppercase here, as
upper/lower case A-Z and a-z are not intermixed in the gaps in A-Z and
a-z under EBCDIC.
toke.c: Fix an ASCII-platform dependency
XXX Dumper.xs: Don't know why this stopped compiling
XS-APItest/t/handy.t: Change output message

On EBCDIC platforms, the output is not in terms of \N{U+}; change text
to \x{ }
re/charset.t: Allow to work on EBCDIC

This just converts the hard-coded character numbers to native, so will
work on any platform.
hints/os390.sh: Suppress bogus compiler message
regcomp.c: Fix bug in EBCDIC

The POSIXA and NPOSIXA regnodes need to set the bits on only the ASCII
code points, but under EBCDIC those code points are 0-127.
XXX: regen/regcharclass.pl: Temp for testing
XXX: Fixup commit message.

Fix UTF8_ACUUMULATE, utf8.c
