Jannis Harder 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.

Jannis Harder a855d62b42 verific: Improve logic generated for SVA value change expressions 
The previously generated logic assumed an unconstrained past value in
the initial state and did not handle 'x values. While the current formal
verification flow uses 2-valued logic, SVA value change expressions
require a past value of 'x during the initial state to behave in the
expected way (i.e. to consider both an initial 0 and an initial 1 as
$changed and an initial 1 as $rose and an initial 0 as $fell).

This patch now generates logic that at the same time

	a) provides the expected behavior in a 2-valued logic setting, not
	   depending on any dont-care optimizations, and

	b) properly handles 'x values in yosys simulation
