Martin Povišer ad149cc42a passes: show: Factor out 'join_label_pieces' 
In two places, we are joining label pieces by a '|' separator. We go
about it by putting the separator behind each entry, then removing the
trailing separator in a final fixup pass on the built string. For easier
reading, replace those occurrences by a new factored-out
'join_label_pieces' function.

Martin Povišer e3709ce776 passes: show: Fix portbox bit ranges in case of driven signals 
When the 'show' pass generates portboxes to detail the connection of
cell ports to wires, it has special handling of signal chunk
repetitions, but those repetitions are not accounted for in the
displayed bit range in case of cell outputs. Fix that, and so bring it
into consistence with the behavior on cell inputs.

So, taking for example the following Verilog snippet,

  module DRIVER (Q);
     output [7:0] Q;
     assign Q = 8'b10101010;
  endmodule

  module main;
     wire w;
     DRIVER driver(.Q({8{w}}));
  endmodule

make the show pass display '7:0 - 8x 0:0' in the driver-to-w portbox
instead of '7:7 - 8x 0:0' which it displayed formerly.

Jannis Harder 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.

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.
