HeAP: Skip high-strength cells in both cell loops. 
Previously only the first loop skipped cells with high belStrength,
but they can't be processed by the second loop either, so skip them
there too.

gatecat 93e34b8754 interchange: Disambiguate cell and bel pins when creating Vcc ties 
The pins created for tieing to Vcc were being named after the bel pin,
relying on the fact that Xilinx names cell and bel pins differently for
LUTs. This isn't true for Nexus devices which uses the same names for
both, and was causing a failure as a result.

This uses a "PHYS_" prefix that's highly unlikely to appear in a cell
pin name to disambiguate.

Keith Rothman 8773c645ca [interchange] Prevent site router from generating incorrect LUTs. 
The previous logic tied LUT input pins to VCC if a wire was unplacable.
This missed a case where the net was present to the input of the LUT,
but a wire was still not legal.  This case is now prevented by tying the
output of the LUT to an unused net.

Keith Rothman c11ad31393 [interchange] Scale edge cost of pseudo pips. 
Previous pseudo pips were the same cost as regular pips, but this is

Keith Rothman a519341112 Fix bug in router2 where router may give up too early. 
Was introduced in #612.  The logic before was intended to prevent the
router from terminating early when not using a bounding box, but the fix
in #612 simply removed that, meaning that the router might terminate
early incorrectly.  The solution here is to only use the toexplore
hysteric once a solution is found.
