a1814b732f flatten: make hygienic. 
Before this commit, `flatten` matched the template objects with
the newly created objects solely by their name. Because of this,
it could be confused by code such as:

    module bar();
      $dff a();
    endmodule

    module foo();
      bar b();
      $dff \b.a ();
    endmodule

After this commit, `flatten` avoids every possible case of name
collision.

Fixes #2106.

6268bdfe6f flatten: simplify. 
`flatten` cannot derive modules in most cases because that would just
yield processes, and it does not support `-autoproc`; in practice
`flatten` has to be preceded by a call to `hierarchy`, which makes
deriving unnecessary.

66255dab4e flatten: simplify. 
Flattening does not benefit from topologically sorting cells within
a module when processing them.

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

76c4ee4ea5 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.

6ac54a74fe 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`.
