Make C<undef ~~ 0> and C<undef ~~ ""> not match (like in 5.10.0)

    This makes ~~ commutative with regard to undef, and fixes an
    inconsistency, since C<undef ~~ [0]> was not matching, and ~~
    should be distributive in this case.

Dave, can you consider this for inclusion in maint ?

No perldelta addition necessary, since we're actually restoring
behaviour that was in 5.10.0.
