Add a hint when a double is printed

[sethladd]

dart2js and vm differ when printing doubles.

  double x = 5.0;
  print("x is $x") ;

vm : 5.0
dart2js : 5

Until Issue #15881 is address, can we give the developer a hint or warning that printing a double results in differing behavior. Giving developers early warnings when code runs differently really helps to shorten the bug cycle.

The issue to watch is now Issue #1533.

This would be a hint. Currently with other bugs and our current resources all hint work is being marked as Later.

Since there are certainly false-positives here, I think this is better suited for the linter.
