Jannis Harder 5042600c0d xprop, setundef: Mark xprop decoding bwmuxes, exclude them from setundef
This adds the xprop_decoder attribute to bwmuxes that drive the original
unencoded signals. Setundef is changed to ignore the x inputs of these
bwmuxes, so that they survive the prep script of SBY's formal flow. This
is required to make simulation (via sim) using the prep model show the
decoded x signals instead of 0/1 values made up by the solver.

Jannis Harder 4a0ed35aab xprop: Improve signal splitting code
Avoid splitting output ports twice when combining -split-outputs with
-split-public and clean up the corresponding code.
