c0063288d6 Add the $anyinit cell and the formalff pass 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
use different backends simultaneously.

5db542742b async2sync: turn FFs with const clks into gclk FFs with feedback 
The formal backends do not support multiple clocks. This includes
constant clocks. Constant clocks do appear in what isn't a proper
multiclock design, for example when mapping not fully initialized ROMs.
As converting FFs with constant clocks to FFs using the global is doable
even in a single clock flow, make async2sync do this.

This adds a -make_assert flag to equiv_make. When used, the pass generates

a const reference is all we need.

1822be8792 Observe $TMPDIR variable when creating tmp files 
POSIX defines $TMPDIR as containing the pathname of the directory where
programs can create temporary files. On most systems, this variable points to
"/tmp". However, on some systems it can point to a different location.
Without respecting this variable, yosys fails to run on such systems.

fc65ea47df select: Fix -assert-none and -assert-any error output and docs 
Both of these options consider a selection containing only empty modules
as non-empty. This wasn't mentioned in the documentation nor did the
error message when using `select -assert-none` list those empty modules,
which produced a very confusing error message complaining about a
non-empty selection followed by an empty listing of the selection.

This fixes the documentation and changes the `-assert-none` and
`-assert-any` assertion error messages to also output fully selected
modules (this includes selected empty modules).

It doesn't change the messages for `-assert-count` etc. as they don't
count modules.
