Marti Alonso 21868f9de7 Consider spare columns when building liberty file 
Spare columns are considered as extra data bits, thus extra pins are
added. However, the data bus size on the liberty file only accounted for
the real data bits. This would cause pin size mismatch issues when using
such macros in OpenROAD and left the whole data port disconnected.

Fix it by properly setting the data bus size. Additionally, add the
spare_wen pins which were also missing.

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.
