t/op/sub_lval.t: Add tests for lvalue subs returning vec() or substr() and
called twice in one expression
Perl prior to v5.20 (at least v5.16.3, v5.18.4) fail to return correct
value from subroutine returning vec() and substr() as lvalue but called
multiple times in rvalue context of one expression:
$ perl -wle 'my $x = "\002"; sub myvec1 :lvalue { vec($x, $_[0], 1) }' \
-e 'print myvec1(0); print myvec1(1); print myvec1(0) + myvec1(1)'

This apparently had been fixed in the commit
169504d53dbeb12d5171b2b44e7db3c2b81af314 (in 2013), but testcases
for these symptoms doesn't seem to exist.
