[perl #122853] Guarantee 0-9, A-Z, a-z character classes

I have now documented the behavior in 09e4339761388239d17da23bf3fa0c882a0b04bf.

In looking at this, I found some bugs in the EBCDIC handling, which are now fixed.

I also changed things so that /[\N{LATIN SMALL LETTER I}-j]/ (and similar) will receive the special handling that /[i-j]/ receives to guarantee the behavior.  This includes the \N{U+...} form, as the "U" means Unicode, and so the behavior should be like what would happen with Unicode.
