Add option to the analyzer (also in Editor) that specifies to assume that the keyword in an type inferred specifier.

Sample code and explanation.

void main() {
  var i = 0;
  i = "";
}

Option turned off (current behavior):
No warrning, because "var" is dynamic type alias.

Option turned on.
Warning: "A value of type 'String' cannot be assigned to a variable of type 'int'".
