Hi all, 

please review the patch which adds new tests for Segmented Code Cache feature. 

Test tries to full code heaps using new WB API function (allocateCodeBlob) added by 8059624 and checks that overflow handling works properly for every code heap. 
Also it checks that compilation is disabled on code cache/heap overflow. 

Added new WB functions: 
- getCompilationActivityMode() to get compilation mode value (stop_compilation, run_compilation or shutdown_compilation) 
- getCodeBlob to get blob object (instance of sun.hotspot.code.CodeBlob class) 

changes in product code: 
- get_compilation_activity_mode() added to compileBroker 

testing: locally 
jbs: https://bugs.openjdk.java.net/browse/JDK-8059550 

------------ 
Thanks, 
Pavel
