...
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 .

`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.

Although the two passes started out very similar, they diverged over

complex while `flatten` does not have to be, and this complexity

Add WASI platform support.
...
This includes the following significant changes:
* Patching ezsat and minisat to disable resource limiting code
on WASM/WASI, since the POSIX functions they use are unavailable.
* Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
does not support spawning subprocesses (i.e. Emscripten or WASI).
This definition hides the definition of `run_command()`.
* Adding a new Makefile flag, DISABLE_SPAWN, present in the same
condition. This flag disables all passes that require spawning
subprocesses for their function.

deminout: prevent any constant assignment from demoting to input
...
Before this patch,
```
module top(inout io);
assign io = 1'bx;
endmodule
```
would have the `io` pin demoted to input (same happens for `1'bz`,
but not for `1'b0` or `1'b1`), resulting in check failures later on.
Part of fix for #1841 .
