petdance/scratch — Issue #545: NQPrx does not vivify globals in all cases

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?
