 This code:
 {{{
 module Z;
 our $Global;
 sub zzz() {
         unless $Global {
                 say("Not set");
         }
 }
 INIT {
         zzz();
 }

 module A;

 sub aaa() {
         our $G2;

         unless $G2 {
                 say("Not set");
         }
 }
 }}}

 generates:
 {{{
     get_global $P21, "$Global"
     unless $P21, unless_20
 }}}

 for the access code in `sub zzz`. There is no guard for null. But in the
 access code in `sub aaa` there is this:
 {{{
     get_global $P31, "$G2"
     unless_null $P31, vivify_17
 }}}
 Apparently the scope isn't being looked up correctly, or something?
