Corrected the use of the global substrate node name; this has been

restricted to its original intent, which is to replace the long name
formed from the plane short name and the "minfinity" coordinate.
This avoids issues with conflicting substrate names derived from a
real layer such as pwell.  Also, the global substrate node name now
returns the variable name without the "$" in front if the variable
has not been set to anything.  This avoids potential syntax errors
in the netlist.

// Modification 9/9/2014 by Tim:
// Convert the treg_ll value up to top-level coordinates.
// Otherwise you end up with a node that is apparently in
// "canonical coordinates", but if you try to find the
// location of the node using the name, you'll end up in
// a random place. It also allows the low-probability
// but possible conflict between this node and another with
// the same name in the parent cell.
//
// Reverted 10/30/2014: Apparently this causes worse
// problems.

// GeoTransPoint(&scx->scx_trans, &reg->treg_ll, &r.r_ll);
