Test language/map_literal4_test fails on dart2js

[sgjesse]

First of all this is a checked mode test, but it will also fail in unchecked mode due to the following construct:

    try {
      var m = const <String, int>{"a": 0};
      m[2] = 1; // 2 is not a String.
    } on TypeError catch (error) {
      result += 100000;
    }

Also the static warnings differ from the analyzer:

tests/language/map_literal4_test.dart:14:37: Warning: "int" is not assignable to "String".
      var m = <String, String>{"a": 0}; // 0 is not a String.
                                    ^
tests/language/map_literal4_test.dart:25:32: Warning: "String" is not assignable to "T".
      var m = <String, T>{"a": "b"}; // "b" is not an int.
                               ^^^
tests/language/map_literal4_test.dart:30:32: Warning: "int" is not assignable to "T".
      var m = <String, T>{"a": 0}; // OK.
                               ^
tests/language/map_literal4_test.dart:35:32: Warning: "int" is not assignable to "T".
      var m = <String, T>{"a": 0};
                               ^

[warning] The element type 'int' cannot be assigned to the map value type 'String' (/usr/local/prj/dart/git/dart/tests/language/map_literal4_test.dart, line 14, col 37)
1 warning found.

This test should probably be rewritten to a multi-test.
