Add assert(Boolean), assert(Boolean, String)

This overload exists for Chisel 2 compatibility (Rocket uses it).

I tried to just add a single extra method ('apply(Boolean, String="")') but
Scala complained about having overloads with implicit arguments.  Instead I
just went ahead and added 4 overloads that do the same thing as the implicit
arguments, just a bit less cleanly.
