Runtime errors on field initializers

The following code compiles, but produces a NaN field:

class A {
 A(double this.a) : b = 1 + this.a;
 final double a, b;
}

A a = new A(0.0); // a.b == NaN

Some variations (for example, if b is a list) throw an runtime exception.

Tested on last trunk version.

Added Area-VM, Triaged labels.

The code above is invalid as accessing this in the initializer list is not allowed. I get this error message instead:

'Issue549.dart': Error: line 2 pos 29: unexpected use of 'this' in primary expression
 A(double this.a) : b = 1 + this.a;
                            ^
Just to clarify, you tried to run this code on the VM?
