Bastian Koppelmann dd1afe0313 Bitcell arrays: Allow mirroring on the y axis 
this allows for bitcells that need to be mirrored on the y axis, like
thin cells. However, the portdata elements also need to be mirrored on
the y axis. Otherwise the router will fail horribly when connecting
bitlines.

Bastian Koppelmann df9f351a91 Add custom cell properties to technologies 
this is technology specific database to store data about the custom
design cells. For now it only contains on which axis the bitcells are
mirrored. This is a first step to support thin cells that need to be
mirrored on the x and y axis.

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.

Bastian Koppelmann c0c89e465a vector: Implement hash cache for vector3d and vector 
this gives us a small runtime improvement in the router.

For FreePDK45 word_size=8, num_words=256

*** Maze routing supplies: 89.8 seconds
** Routing: 279.3 seconds

Non-improved
*** Maze routing supplies: 105.1 seconds

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

Improved
**** Analyzing pins: 20.9 seconds
** Routing: 293.8 seconds
** SRAM creation: 349.8 seconds

Non-improved
**** Analyzing pins: 267.9 seconds
** Routing: 537.5 seconds
** SRAM creation: 592.9 seconds

Bastian Koppelmann 1df16eceb6 sram_factory: Give proper priority to overrides 
modules overridden by the user are the highest priority, then modules
overridden by the technology. If nothing is overriden, use the defaults
from OPTS (if they exist) or use the requested module_type.

This fixes that custom tech_modules could not be used, if they had a default in
OPTS even if the latter was not overridden by the user.

We don't need extra defaults in the tech_modules, as we now only use them,
if they have been overridden by the tech_module.
