The loop tutorial didn't have any POD, so I added POD talking about how PIR
doesn't have looping constructs, aside from using goto in a loop.

+=head1 Loops
+
+PIR has no built-in looping structures such as C<for>, C<while>, C<repeat> or
C<until>. All
+loops are built by using conditionals and C<goto>.
+
+The loop below calculates 5 factorial, stored in C<$I0>. C<$I1> is the loop
counter.

.sub main :main
$I0 = 1 # product
