RFR: 8145471: javac changes for enhanced deprecation

[Jan Lahoda]

Overall, seem OK to me. Two comments:
-is the change in make/CompileJavaModules.gmk really needed given the 
adjusted JAVAC_WARNINGS in make/common/SetupJavaCompilers.gmk?

-the reliance on literal "true" in TypeEnter seems suspicious to me. 
What if the value of the attribute is a compile-time constant? I suspect 
this may be non-trivial to fix, so no strict need to fix that under this 
patch, but I think we should have a good idea how we want this fixed, 
and there should be a JBS entry filled for that.
