9c6198a827 sim: Internal API to set $initstate 
This is not yet added to any of the simulation drivers.

44b26d5c6d sim: Emit used memory addresses as signals to output traces 
This matches the behavior of smtbmc.

This also updates the sim internal memory API to allow masked writes
where State::Sa bits (internal don't care - not a valid value for a
signal) leave the memory content unchanged.

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.
