If we're targeting a JS backend, `isSubtype` considers every int to be a double. We need to additionally allow any integer-valued double to be an int. This mainly allows us to handle signed zeroes correctly. Fixes https://github.com/dart-lang/sdk/issues/36562.

Run Existing Tests ================== See the output of ../tools/test.py --help for how to run tests. See also https://code.google.com/p/dart/wiki/Building#Testing for detailed examples. Create New Tests ================ See comments above factory StandardTestSuite.forDirectory in ../tools/testing/dart/test_suite.dart for the default test directory layout. By default test-file names must end in "_test.dart", but some test suites, such as ./co19, subclass StandardTestSuite and override this default. See comments at the beginning of ../tools/testing/dart/multitest.dart for how to create tests that pass by failing with a known error. For example, ... int x = "not an int"; /// 01: static type warning ... as part of a test will only pass the "--compiler dart2analyzer" test if the assignment generates a static type warning.
