Enable GVN for all HFieldGet.

Mark all non-final HFieldGet as depending on something.

Next step: figure out why GVN does not use the value of a.x computed
before the conditional in the following example:

class A {
  int x;
  bool b;
  A(this.x, this.b);
}

main() {
  A a = new A(42, true);
  var x = a.x;
  if (a.b) x = a.x + a.x;
  return x;
}

Move frog/tests/{leg,leg_only,frog_native} to tests/compiler/. 

This may not be the final resting place for these tests, but I want 
to get them out of the frog directory because they really are very
valuable as tests for dart2js.

Prototype re-compiling methods in dart2js

This is a prototype with the ability for dart2js to retry the
compilation of a method after everything has been compiled
once. Information collected during the first compilation can then be
used when retrying the compilation.

During compilation information on whether setters are used on specific
fields is collected. When compilation is retried and there are no
setters for a field it is treated as if it was declared final.

As this is a prototype there are some issues we need to discuss, e.g.

* The two queues should probably be generalized some way - maybe with
  listeners on specific changes to the collected information

* Throwing Pass2BailoutException when retrying compilation is a bit of
  a hack. We should probably not try to retry something we can't.

* Where to store the imformation collected during compilation

This is one way of improving Delta Blue with 25-30%.
