mrg d609e4ea04 Reimplement trim options (except on unit tests). 
Allow trim netlist to be used for delay and functional simulation.
Each class implements a "trim_insts" set of instances that can be removed.
By default far left, right, top and bottom cells in the bitcell arrays are kept.

Use lvs option in sp_write

Fix lvs option in sram.

Bastian Koppelmann 9749c522d1 tech: Make power_grid configurable 
this is the first step to allow engineers, porting technologies, more room
for routing their handmade cells.

For now, we don't allow the specification of power_grids where the lower layer
prefers to be routed vertically. This is due to the router not
connecting some pins properly in that case.
