This symbol goes unused in this commit, but the next version of perl
that we build changed the name of the symbol, so rename it here by
backporting this patch.

Only the part of the patch changing the name is used. The other two
modifications in the original patch change the use of the symbol
which obviously does not apply to this build.

Subject: [PATCH] Rename property involved in \X matching, for clarity

I was re-reading some code and got confused.  This table matches just
the first character of a sequence that may or may not contain others.
