In-each declaration at file top-level are not correctly tracked

[JonatanWaern]

Simple example:

bank b {
    register r; // Will error that 'offset' has not been set
    in each (register) {
        param offset = 4;
    }
}

Similar error does not appear if r instantiates a template setting offset, or if it sets offset directly.

This issue is more general than I expected. For example:

template t {
    param p = 0;
}
group g is t {
    param a  = p;
    param b = q;
}
in each (t) {
    param q = 0;
}

Here, references fail to bind both p -> definition of p in t and q -> definition of q in in each.

Likely, something broke when locals-in-methods were fixed

Narrowed this down to new title.

template t {}
group g is t {
    param a  = p;
}
in each (t) {
    param q = 0;
}

does not work, but

template t {}
group g {
    group h is t {
        param a  = p;
    }

    in each (t) {
        param q = 0;
   }
}

does

This also implies to in-eachs declared in imported files, so its not an issue related to the main device analysis faux spec.

Fixed as part of #133
