Handle repeat concatenation in continuous assign
Handle repeat concatenation in continuous assign

When a repeat concatenation expression is translated to a netlist,
get the repeat expression right. This comes up when an elab_and_eval
elaboration contains a repeat concationation, and the expression is
ultimately turned into a netlist by expr_synth.
