RFR: JDK-8055735: JDK_FILTER is broken

[Erik Joelsson]

After the source code restructure, the JDK_FILTER functionality is not 
working well. The first module that needs to be recompiled gets the 
filter applied, but then the dependents also get it and the macro finds 
zero files and fails the build. I have created a fix for this that makes 
the build pass, but JDK_FILTER is still not functioning very well.
