Bastian Koppelmann 656fdd1008 port_data: Refactor channel_route/connect_bitlines() 
both functions share a lot of code and are passing around a lot of data
under similar names (inst1, inst1_start_bit, inst1_bl_name, ...). Thus
we group all these elements in a named tuple to ease passing around
these elements.

All callers of channel_route/connect_bitlines() either pass in the bl/br
names or rely on "br_{}"/"bl_{}" as defaults. These hard coded values
should be determined by the instances. Thus we get the bitline names
based on the instances passed in. The callers only provide a template
string, to take care of the case that bitlines are called "bl_out_{}".

Bastian Koppelmann 5e1f64c8f9 modules/port_data: Add get_bl/br_name method 
if we rely on the names of the submodules (sense_amp_array,
write_driver_array, etc.) for port_data's pins, we get into trouble on
multiport SRAMs. To avoid this we use explicit names for br/bl depending
on the port number in port_data. Now each submodule does no longer need to
figure out the right name depending on the port number.

Bastian Koppelmann f9babcf666 port_data: Each submodule now specifies their bl/br names 
before the names of bl/br from the bitcell were assumed. If we want to

modules from that. Note, that we don't touch every occurence of bl/br,
but only the once necessary that pin renaming of the bitcell works.

Bastian Koppelmann 7ff5121d8c base/pin_layout: Implement hash cache 
the hash value only depends of the properties 'rect' and 'layer' so we
only compute the hash if those values are changed. Otherwise we just
return the precomputed value. This gives us a major speedup (~10x) if
the hash is used as a key in a dict.

During the grouping of pins in analyze_pins() this gives the best
improvements. For example for FreePDK45 with num_bits=8, num_words=256

**** Analyzing pins: 20.9 seconds
