flatten: simplify. NFC.
...
Flatten is non-recursive and doesn't need to keep track of handled
cells.

techmap, flatten: remove dead options.
...
After splitting the passes, some options can never be activated,
and most conditions involving them become dead. Remove them, and also
all of the newly dead code.

flatten: split from techmap.
...
Although the two passes started out very similar, they diverged over
time and now have little in common. Moreover, `techmap` is extremely
complex while `flatten` does not have to be, and this complexity
interferes with improving `flatten`.
