[drlvm][win64] Double.doubleToLongBits(double) produces incorrect results.
--------------------------------------------------------------------------

                 Key: HARMONY-3365
                 URL: https://issues.apache.org/jira/browse/HARMONY-3365
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Mikhail Fursov
            Priority: Critical


While debugging DRLVM on WIN64 platform I've found that Double.doubleToLongBits(double) method
produces incorect results and prevents some benchmarks to pass.

Here is the test:
    public static void main(String[] args) {
        System.out.println(Double.doubleToLongBits(1));
    }

RI prints:
4607182418800017408

Harmony (both JET and OPT)
-3689348814741910324

I think the cause is a problem in native stubs and calling conventions on windows in DRLVM.
