Add qr/\b{gcb}/
A function implements seeing if the space between any two characters is
a grapheme cluster break. Afer I wrote this, I realized that an array
lookup might be a better implementation, but the deadline for v5.22 was
too close to change it. I did see that my gcc optimized it down to
an array lookup.
This makes the implementation of \X go from being complicated to
trivial.
