The serializer doesn't correctly propagate environment information
from try blocks into their catch handlers, and this impedes
optimizations that fire when we compile concurrently.

function bar(x) {
  try {
    boom(); // throws
  } catch(_) {
    return x.a;
  }
}

function foo() { return bar({a: 42}); }

When foo is optimized, we can normally return the constant 42
directly. This CL makes that work for concurrent inlining.
