Jannis Harder 7203ba7bc1 Add bitwise `$bweqx` and `$bwmux` cells 
The new bitwise case equality (`$bweqx`) and bitwise mux (`$bwmux`)
cells enable compact encoding and decoding of 3-valued logic signals
using multiple 2-valued signals.

Jannis Harder 605d127517 simlib: Silence iverilog warning for `$lut` 
iverilog complains about implicitly truncating LUT when connecting it to
the `$bmux` A input. This explicitly truncates it to avoid that warning
without changing the behaviour otherwise.

Jannis Harder b982ab4f59 satgen, simlib: Consistent x-propagation for `$pmux` cells 
This updates satgen and simlib to use a `$pmux` model where the output
is fully X when the S input is not all zero or one-hot with no x bits.

Jannis Harder 661fa5ff92 simplemap: Map `$xnor` to `$_XNOR_` cells 
The previous mapping to `$_XOR_` and `$_NOT_` predates the addition of
the `$_XNOR_` cell.
