VM crashes on too-large new List(n) argument.

[lrhn]

Example code:
  new List(268435456); // Smallest number triggering crash on IA32.
Gives:
runtime/vm/object.cc:19102: error: Fatal error in Array::New: invalid len 268435456

Aborted (core dumped)

The mentioned line is commented as:

    // This should be caught before we reach here.
    FATAL1("Fatal error in Array::New: invalid len %" Pd "\n", len);

so the comment seems to not hold.
