Aki Van Ness a90f940615 backends/firrtl: Ensure `modInstance` is valid 
This should fix #3648 where when calling `emit_elaborated_extmodules` it
checks to see if a module is a black-box, however there was no
validation that the cell type was actually known, and it just always
assumed that we would get a valid instance, causing a segfault.

Jannis Harder 5e82638408 smt2: Fix operation width computation for boolean producing cells 
The output width for the boolean value should not influence the
operation width. The previous incorrect width extension would still
produce correct results, but could produce invalid smt2 output for
reduction operators when the output width was larger than the width of
the vector to which the reduction was applied.

This fixes #3654

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.

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.
