RFC: JWarmup precompile java hot methods at application startup

[yumin qi]

Alan,
  Thanks! Updated in same link:
  http://cr.openjdk.java.net/~minqi/8220692/webrev-02/

  Removed non-boot loader branch in nativeLookup.cpp.
  Added jdk.jwarmup to boot loader list in make/common/Modules.gmk.
  Tested again to make sure the new changes.

  Thanks
  Yumin
