LGTM.

lib/compiler/implementation/ssa/tracer.dart:426: return result.toString();
I kind of like doing this in this way:

   var on = node.isOn ? "on" : "off";
   var id = temporaryId(node.guarded);
   return "TypeGuard($on): $id is $type env: $buffer";

and get rid of the first result.add() calls. WDYT? I think it makes the format
easier to grok.
