[jdk7u-dev] Please review the fix for 7126832

[Jim Holmlund]

Here is the bug:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7126832

Here is the webrev
http://cr.openjdk.java.net/~jjh/7126832/

The fix is the same as the fix in jdk8 with one exception:
- in JDK 8, the compile(...) methods in Main.java return Result whereas in JDK 7 they return int
- the patch adds a new compile method, so in 8 this new method is
          public Result compile(String[] args,   .....

   whereas in 7u-dev, it is
          public int compile(String[] args,   .....

Here is the patch in jdk 8:

Testing:
    - langtools built and regression tests run on Windows

Thanks
