Fwd: RFR: 8005204: Provide more detailed output on CodeCache usage

[Alexander Harlap]

  AdapterHandlerLibrary::get_adapter() in sharedRuntime.cpp  has 
ResourceMark rm;
AdapterHandlerLibrary::create_native_wrapper in shared Runtime.cpp has 
ResourceMark rm;

CompileBroker::compiler_thread_loop() in compileBroker.cpp has 
ResourceMark rm;
SharkCompiler::compile_method (it calls env->register_method())  has 
ResourceMark rm;

Compile::Compile calls   env->register_method() calls  
CompileBroker::handle_full_code_cache() -none has ResourceMark.
