Implement correct parametrized types for factories

[ghost]

This test crashes in debug mode:
./vm/ast.h:1689: error: expected: type_arguments_.IsNull() || (type_arguments_.Length() == Class::Handle(constructor_.owner()).NumTypeArguments())

Once the crash is analyzed and eliminated, feel free to lower this issues's priority.

FactoryNegativeTest.dart:

main() {
  // Compile time error, wrong factory method.
  var a = new Link<int>.create();
}

interface Link<T> factory LinkFactory {
  Link.create();
}

class LinkFactory {
  // Compile time error: should be Link<T>.create().
  factory Link.create() {
    return null;
  }
}

The crash has been eliminated, an error is reported.

Removed Priority-Critical label.
Added Priority-High label.

Proper factory syntax was implemented by the VM in r1595.
dartc and frog have to implement it too, so that all libraries can be fixed.
Reassigning to dartc area.

Eric, could you take a look at this issue? We should definitely support parsing and static type checking. I'll leave it up to you to make a recommendation on code generation support for this.

Also, I believe that it is section 8.3 of v0.5 of the spec that covers this. Ivan mentioned that the map.dart, hash_map_set.dart have commented out code that demonstrate the syntax. You will see comments marked with issue #417.

as of r2004, the parser will start accepting the new syntax for factory methods, (but nothing will be done with the types).

The revised factory syntax is supported in the VM in r2394.
The old factory syntax is still supported, but warnings are issued.
